Funding opportunity

Funding opportunity: National Fellowships in Fluid Dynamics (NFFDy)

Apply for a postdoctoral fellowship of up to three years in any science, technology, engineering, and mathematics (STEM) area related to fluid dynamics.

You must:

  • have completed, or be close to completing, a PhD in a related field
  • be able to undertake the fellowship at an eligible research organisation.

You will also need to:

  • have an idea for a programme of work that will deliver research with a focus on fluid dynamics
  • collaborate with the existing UK fluids community as part of your work.

Funding will be at 80% of the full economic cost, which may cover the fellowship salary, research consumables and travel costs.

Who can apply

Standard EPSRC eligibility rules apply. Research grants are open to:

  • UK higher education institutions
  • research council institutes
  • UK Research and Innovation (UKRI)-approved independent research organisations
  • public sector research establishments
  • NHS bodies with research capacity.

Check if your institution is eligible to apply for funding.

Individual eligibility

You can apply if you either:

  • have a PhD
  • expect to have submitted your thesis by December 2022.

We encourage applicants who have taken a non-standard career path after their first degree. We also welcome applications from candidates who want to move back into research after a career break, or any other type of break from active research. There are no restrictions on nationality.

You will need to be hosted by an eligible UK research organisation during your fellowship. A host organisation statement will be required for the ‘full proposal’ stage.

This funding is intended for postdoctoral-stage researchers.

You are not eligible to apply if you:

  • already hold a permanent full time academic position
  • have previously held a significant grant, usually defined as those which included postdoctoral research award time, capital equipment or were in excess of £100,000 full economic costs.

If you have already been in receipt of significant funding as defined above, or have been leading in an area of technical development, you may wish to apply for an EPSRC open fellowship.

We will not accept uninvited resubmissions of projects that have been submitted to UKRI or any other funder.

Submissions to this funding opportunity will not count towards the EPSRC repeatedly unsuccessful applicants policy.

For more information about postdoctoral fellowships, read our postdoctoral and open fellowships guide.

Host organisation support

Research organisations may wish to show their commitment to applicants by providing additional support and resources. Read the host organisation statement for more details.

What we're looking for

NFFDy aim to support a cohort of postdoctoral fellows for up to three years.

A key objective of this scheme is to connect the NFFDy fellows with the UK fluids community as they write their proposals so that the fellows will be supported by the community and will align their research to areas of significant long term interest to the UK. The NFFDy Hub has been funded by EPSRC and set up for this.

Visit the NFFDy Hub.

Other objectives are to provide fellows with resources, mentoring and training to help them pursue their research vision: to encourage the fellows to advocate more broadly for fluid dynamics, and to horizon scan for new research ideas.

This fellowship is a personal award for future leaders with current expertise in engineering, physical, environmental or biological sciences, with an emphasis on fluid dynamics or data science.

It’s designed to provide you with the necessary support to gain skills and expertise to propagate and apply techniques from data-driven fluids to myriad applications globally.

As a fellow, you would be provided with a salary and significant resources to pursue your career and make the leap from postdoctoral to principal investigator level.

About you

You could consider applying for a postdoctoral fellowship if you:

  • have recently started formulating your own research ideas for programmes of work up to three years in duration that will deliver high quality research with a focus on fluid dynamics
  • can demonstrate that you have acquired the skills and expertise to deliver your research proposal successfully
  • have identified training and development needs to enable you to prepare for an enhanced career in research and innovation.


Your research can be curiosity-driven or industrially-motivated, or a combination of both.

In your proposal you will need to:

  • demonstrate that you have a research idea related to fluid dynamics
  • show how you will collaborate with the existing UK fluids community, whether academic or industrial (for example, through the existing special interest groups of the UK Fluids Network or the creation of a new special interest group)
  • identify which research communities would benefit from the outcomes.
  • show an interest in problems outside of your own area of expertise
  • demonstrate that you will be capable of communicating your research to the community outside of your immediate discipline.

You will also be expected to attend the two summer programmes organised by the NFFDy Hub or, if unable to attend, you advise us on other ways you could engage with the cohort of NFFDy fellows.

Your proposed area of research must predominantly fit into EPSRC’s current remit (at least 50%).

Read the full list of EPSRC research areas.

If you are successful in your application, you will be expected to start your fellowship between January and June 2023.

What we will expect of you

As a NFFDy fellow, you will be expected to:

  • have an international outlook
  • be open-minded about new problems and take an interest in problems outside your own area of expertise
  • seek to make the most of being based in the UK, for example by leveraging the UK Fluids Network
  • be enthusiastic about taking on a position of technical leadership within an existing or new special interest group within the UK Fluids Network and communicating your research to people outside your immediate discipline
  • aim to have a positive impact on UK fluid dynamics and the UK more broadly, for example, by addressing the UK’s societal or industrial challenges.

For project ideas to address UK challenges, you may want to read our fluid nation: the impact of fluid dynamics in the UK.

By the end of your fellowship, you should be an agile, multidisciplinary, independent research leader who has developed deep, broad and flexible expertise in fluid dynamics.

Successful fellows will be expected to use their awards to contribute to:

  • promote the development, sharing and exploitation of high-quality, sustainable research in fluid dynamics
  • demonstrate leadership in the fluid dynamics research communities and acting as ambassadors and advocates for UK fluid dynamics research
  • facilitating knowledge transfer by fostering collaborative relationships with academic and industrial partners both in the UK and internationally.

Connecting with the community

We recommend that you discuss your ideas with others in the fluids community to develop your proposal.

The NFFDy Hub has been funded by EPSRC and set up to facilitate the exchange of ideas between applicants and the UK fluids community. Connect with the NFFDy Hub.

Visit the UK Fluids Network for access to a directory of UK fluid dynamics researchers listed by subject and institution.

Summer programmes

As an NFFDy fellow, you will be part of a cohort and will be encouraged to attend two summer programmes, the first of which will be on ‘data in fluids’ with two weeks of lectures and tutorials followed by four weeks of projects. At these programmes, you will participate in training and work on projects at the intersection of data-driven and physics-based modelling, either with experimental or numerical data or both.

The facilitator of the UK Fluids Network is available to discuss mechanisms to enable attendance by fellows with, for example, caring responsibilities.

Contact the UK Fluids Network facilitator.

Fellowship benefits

Benefits for fellows include:

  • support and advice from the UK fluids community as you are writing your proposal
  • cohort activities during the fellowship, such as fortnightly informal coffee mornings online, a monthly internal seminar series online, and a mentorship scheme
  • a guaranteed place at the UK fluids summer programmes in Cambridge (2023) and Leeds (2024).

What we will fund

You can apply for up to a maximum of three years of funding for a postdoctoral stage award. We will also allow fellowships over shorter periods. You can spend between 50% and 100% of your time on a fellowship.

If you want to work part-time, you can hold your EPSRC fellowship part-time as well, at a minimal level of 50%. In these circumstances, the duration of your fellowship can be extended pro rata.

We will fund 80% of the full economic costs of your project. You may request funding for:

  • equipment and other items needed to carry out the project
  • costs related to impact
  • travel and subsistence.

We will not fund costs for additional researchers on postdoctoral fellowships or individual items of equipment over £10,000 (including VAT).

Read the full equipment guidelines.

Responsible innovation

EPSRC is fully committed to developing and promoting responsible innovation. Research has the ability to not only produce understanding, knowledge and value, but also unintended consequences, questions, ethical dilemmas and, at times, unexpected social transformations.

We recognise that we have a duty of care to promote approaches to responsible innovation that will initiate ongoing reflection about the potential ethical and societal implications of the research that we sponsor and to encourage our research community to do likewise. Therefore, you are expected to work within the EPSRC framework for responsible innovation.

If you plan to include international collaborators in your proposal, you should work to get the most out of international collaboration whilst protecting intellectual property, sensitive research and personal information.

How we will assess your application

Assessment process

There will be a multiple stage submission process, with expressions of interest considered by an expert sift panel, after which invited full proposals will undergo postal peer review.

The proposal, the peer reviewers’ comments and your response will then go to a panel that will score it against our assessment criteria and rank it with other proposals. The top selected candidates will be invited to interview. Interviewed candidates will be informed of the decision by December 2022, and if your application was successful you will be expected to start between January and June 2023.

In the event of this funding opportunity being substantially oversubscribed as to be unmanageable, EPSRC reserves the right to modify the assessment process.

Assessment criteria for the expression of interest

Vision of the research idea

We will assess:

  • how exciting the research idea is and how suitable it is for a three year fellowship
  • the idea’s potential to grow into a research activity that can be sustained in the UK over a 10 to 15 year timescale

About the NFFDy fellowship scheme

The NFFDy fellowship scheme aims to address the emerging need for advanced training in fluid dynamics to manage and interpret the data generated by:

  • computational fluid dynamics
  • laboratory experiments
  • real-world observational measurements.

The NFFDy fellowships provide a route for the most talented PhD graduates in fluid dynamics to stay in this research area and to contribute to the advancement of the field in the UK.

The NFFDy scheme recognises that fluid dynamics is a key contributor to the UK’s strategically important policy objectives of:

  • route to net zero
  • productivity and resilience
  • levelling up
  • sovereign capability.


The UK has a traditional and ongoing strength in fluid dynamics, as well as a wealth of industries that benefit from the UK’s strength in this underpinning discipline. Fluid dynamics research, in addition to being vital for the UK economy, is providing essential fundamental knowledge required to solve some of the grand challenges facing today’s society. These include:

  • clean energy
  • climate change
  • extreme weather
  • virus control
  • pandemic response
  • biofluids and health
  • air quality
  • space weather.

For more information on fluid dynamics-related challenges to society, read our fluid nation: the impact of fluid dynamics in the UK.

EPSRC has provided significant doctoral training via the Centres for Doctoral Training in fluid dynamics at different institutes across the UK. Other UKRI councils have also significantly invested in training for research students in fluid dynamics.

Several hundred students graduate with fluid dynamics PhDs each year, but there are currently many fewer postdoctoral positions or fellowships available in the UK. There is a pressing need for broadening of training at the postdoctoral level, particularly at the intersection of data-driven and physics-based modelling and exposure to experiments and numerics.

To address this issue, the engineering theme at EPSRC has launched the national fellowships in fluid dynamics scheme. It’s been designed to maintain and enhance the world-leading position that the UK has established in fluid dynamics over decades. It encourages a cohesive cohort of elite researchers to advance exciting and creative approaches in fluid dynamics.

The UK Fluids Network has brought together industrial and academic researchers across UK institutions to focus on several dozen applications and methods through the special interest groups. The network has coordinated bottom-up research ideas and strategic vision across the field.

The highly successful UK Fluids Network will provide:

  • centralised coordination activity to support alignment to national challenges
  • the administration of the scheme during the lifetime of the fellowships
  • cohort training based at selected institutions.

Fellows funded through the current NFFDy scheme would flourish within this research environment. They would be inspired by the problems identified by the existing special interest groups and create their own research directions within existing or new groups.
