Dr James Jewkes

I am a fluid mechanics lecturer with a background in the computational fluid dynamics (CFD) simulation of turbulent flows. My research interests range from large-eddy simulation of turbulent jets and boundary layers, to the haemodynamics of the left descending coronary artery, and more recently to the optimisation of high pressure die casting mould cooling channels. My MEng (1st) in Mechanical Engineering was awarded at Warwick University in 2002 followed by a PhD in large eddy simulation (LES) at Warwick in 2008 supervised by (the late) Professor Peter Carpenter and Dr Yongmann Chung. I have worked for IBM UK, Prodrive, and TotalSim UK, and for various universities including Curtin University in Western Australia, the University of South Wales, and Coventry University. In November 2021 I became a Lecturer of Industrial Fluid Mechanics at the University of Leicester. I have held grants as CI from the Australian Research Council and Innovate UK and am currently PI on EPSRC EP/V02695X/1 “Better Bubblers: Jet Impingement Within a Dead-End Channel”.

- EC Grant G4RD-CT-2002-00748 “Aeromems II : Advanced aerodynamic flow control using MEMS."", employed as a research associate on this project during my PhD in the large-eddy simulation of turbulent boundary layers and jets at Warwick University.

Other activities:
- Reviewer for various journals including Journal of Biomechanics, Physics of Fluids and the AIAA Journal.
- Member of the EPSRC Associate Peer Review College.
- Three journal papers included in the REF2021 submission at Coventry University.
