Data-driven modelling of laminar-turbulent transition in wall-bounded flows

Transition from a laminar to a turbulent state in a fluid flow is a widely observed phenomenon occurring in a large variety of natural and engineering applications. Understanding under which conditions laminar-turbulence transition takes place, as well as the dominant mechanisms at play, is crucial for the development of reliable models, and for the implementation of effective control strategies [1]. The aim of this project is to provide a data-driven characterization of laminar-turbulence transition in wall-bounded flows, combining fluid dynamics, data analysis, and network theory within a multidisciplinary framework. The project will be mainly numerically/theoretically oriented, but experimental work exploiting one of EPSRC’s National Wind Tunnel Facilities could be included.

A later start date of October 2022 is also possible.

We are seeking highly motivated candidates with degrees in a relevant engineering field (e.g., aeronautics, environmental, civil, mechanical), as well as physical sciences or applied mathematics, with excellent communications skills, and a strong inclination towards multidisciplinary research. UK and international students holding a first-class degree (or a good 2:1) in the aforementioned disciplines and a background in fluid mechanics are encouraged to apply. Previous experience with Matlab (or Python) computing is essential for the data analysis and code development; some exposure to experimental work would be beneficial.

If English is not the first language, IELTS 6.5 or above (or equivalent) is required, with no sub-test score less than 6.
