Overview

This PhD program focusses on very fast, high-fidelity computational fluid dynamics solvers to model steady-state airframe aerodynamics. It builds on significant advances in computational science and engineering software frameworks designed to maximise performance on CPU and GPU based high performance computers. The resultant solver will provide results which can be used to calibrate surrogate models based either on empirical predictions or machine learning models trained from the CFD data. This project is in collaboration with Thales UK and will benefit from their significant expertise in airframe aerodynamics.

Project Description and Objectives:

In early stage design the aerodynamic performance of an airframe needs to be understood at all the operating points within the flight envelope. The combination of e.g. Mach number, incidence angle, roll angle, wing deflection angles …means that a full data set can consist of tens or even hundreds of thousands of operating points, quickly escalating with increasing resolution of the operating space.

Computational fluid dynamics (CFD) is often used to predict airframe performance. The drawback of this approach is that it can often take several hours to model a single operating point, making characterising the full flight envelope impractical. Less complex one-dimensional or empirical aerodynamics tools also exist. These are accurate when the geometry or operating conditions are close to that used to calibrate the models but have more limited capability to extrapolate to conditions outside of those for which they are calibrated.

In the next decade the best approach to generating large scale databases will consist of high-fidelity computational fluid dynamics coupled with either or both of simpler aerodynamic codes and machine-learning based approaches. Both possible directions require a fast high-fidelity CFD to set the ground truth and/or generate training data. This forms the motivation for the PhD program.

You will adopt and advance open-source CFD solvers able to be run on mixed architectures containing both CPUs and GPUs. Key advancements will focus on the design and implementation of numerical methods for steady state external aerodynamics formulated in a way which scales efficiently on CPU and GPU hardware architectures.

During this PhD you will undertake industry placements within the Aerodynamics team at Thales Belfast where you will gain an insight into the industry drivers for your research, and work with the aerodynamics team to translate your research in the later stages of the project.

Key transferable skills developed:
Through this PhD you will develop: (i) a cutting-edge understanding of numerical methods for aerodynamics, (ii) an ability to program solvers for high performance computing on national level computers and (iii) a fundamental understanding of airframe aerodynamics and (iv) an ability to effectively present your research at international conferences and in top international journals.

Impact and Future Career Prospects:
Our research group is recognised globally for our contributions to computational fluid dynamics methods and applications. PhD graduates in computational science and engineering are in exceptionally high demand thanks to their exceptional grasp of complex governing models, numerical methods and programming on national-level high performance computing facilities.

This PhD program also benefits from a close collaboration with industry partner Thales UK. This will include working at Thales UK where you will benefit from their significant expertise in airframe aerodynamics, and translation of research outcomes into impact at Thales UK. This will further boost your future employability.

Innovation and Interdisciplinarity:
Two key innovations in this project are:
1. Advancement of CFD methods which may be formulated for fast solution on mixed hardware architectures

2. Close collaboration with end users to ensure that methods development is tightly coupled with application needs.

Aerospace Engineering overview

Our society needs exceptional engineers who can understand, create and harness technology to address our shared global challenges. Without these individuals our long-term success as technologically advanced societies and economies will be diminished. Undertaking a PhD in the School of Mechanical & Aerospace Engineering will enable you to make a real difference, positively impacting your career and through your research improving engineering methods and practice, and ultimately society.

Research undertaken by PhD students in the School of Mechanical & Aerospace Engineering forms a critical part of our research portfolio. Our research portfolio is ranked 24th in the UK with 96% of our Engineering research rated as world-leading or internationally excellent [REF 2021/ Times Higher Education]. What is more the REF2021 assessment, which is carried out by panels of academics and international experts, rated over 99% of the university research environment as world-leading or internationally excellent. Within this environment our PhD students research within the broad topics of design, materials, manufacturing, and energy.
Joining us as a PhD student you will be part of a dynamic environment and will study alongside students from many countries worldwide. It is a lively community of over 100 students, in which you will have the opportunity to develop both career and life skills, for example by participating in cohort training and mentoring programmes and student led social and cultural activities.

A PhD studentship is an investment in your personal development, worth over £100,000. Many of our PhD graduates take-up academic roles, while others go on to play leading roles in industry or become entrepreneurs. A PhD provides many benefits, among others it provides a range of “transferable skills”, such as independent and critical thinking, analytical and problem solving skills, leadership, and self-confidence. Because of these developed characteristics we see that many industry leaders hold a PhD. You will likely get a higher salary after graduation from a PhD than you do three years after an undergraduate degree. More importantly, you will get a different type of job and likely make progress faster through promotion and reward mechanisms. This, of course, depends on your ambition, but a PhD builds an exceptional career foundation.
