Turbulence is a well-known flow phenomenon observed ubiquitously in many applications and plays a key role in increasing momentum and heat transfer in various systems. Control of turbulence has been the subject of interest in many disciplines and, to achieve optimal control, it is essential to understand laminar-turbulent transition, the process of how laminar flows become turbulent. The transition and turbulence have been well studied for incompressible flows, but less is known for the transition in compressible flows in which the fluid compressibility introduces additional phenomena such as heat transfer, acoustic waves or even shocks if the flow is supersonic. In particular, a theoretical understanding of how compressible shear flows become unstable and turbulent via the transition is still lacking. This motivates our project with an objective to investigate mathematically and numerically laminar-turbulent transition in compressible shear flows using state-of-the-art approaches. Through the project, we aim to advance our understanding of compressible turbulence and achieve a new methodology for optimal flow control. Eventually, this project will aim to inform the design of various flow systems such as aerial vehicles or compressible blades where the drag and heat transfer on the surface need to be reduced.
Training and Development
The successful candidate will receive comprehensive research training including technical, personal and professional skills.

Entry criteria for applicants to PhD
· A bachelor’s (honours) degree in a relevant discipline/subject area with a minimum classification of 2:1 and a minimum mark of 60% in the project element (or equivalent), or an equivalent award from an overseas institution.
PLUS
· the potential to engage in innovative research and to complete the PhD within 3.5 years
· An adequate proficiency in English must be demonstrated by applicants whose first language is not English. The general requirement is a minimum overall IELTS Academic score of 7.0 with a minimum of 6.5 in each of the four sections, or the TOEFL iBT test with a minimum overall score of 95 with a minimum of 21 in each of the four sections.

In addition to the candidate specification above it is expected that the successful candidate holds or be on course for a BSc or MSc degree in mechanical or aerospace engineering, applied mathematics, or physics. The candidate should be motivated to perform theoretical analyses (e.g. stability analyses) and numerical simulation with knowledge of programming languages such as C++, Fortran, MATLAB, etc. Experience with parallel computing is seen as an advantage but not a requirement.
Informal enquiries are required and should be addressed to Dr Junho Park ([Email Address Removed]). Please send a full CV and transcript of grades before completing the Coventry application process.
