Research Fellow in DNS of compressible flows over rough surfaces

Aeronautical and Astronautical Engineering

Location:  Highfield Campus
Salary:   £30,942 to £34,804
Full Time Fixed Term (until 31/03/2022)
Closing Date:  Friday 24 July 2020
Reference:  1272020DA

You will join our Aerodynamics and Flight Mechanics (AFM) Research Group at the University of Southampton which comprises of experts in theoretical, computational and experimental fluid mechanics and our aim is to provide an environment in which these different approaches can be combined and focused on particular topics of practical importance. You will join a vibrant team of other postdoctoral researchers and graduate students working in different areas of fluid mechanics ranging from environmental flows to hypersonics. 

You will work with Dr. Ralf Deiterding and Prof. Neil Sandham and concentrate on using a high-order accurate Cartesian hybrid WENO/Centered Difference (CD) method with embedded boundary capability to carry out direct numerical simulations (DNS) of fully compressible turbulent boundary layer flows over realistic rough surfaces. The WENO/CD solver is already fully implemented in the massively parallel adaptive solver framework AMROC and has been extensively validated. The aim of the present work is to understand how key surface quantities, like for instance heat flux, are related to flow and roughness. To this end, post-processing specific to turbulent flows over rough surfaces will need to be implemented. A database of compressible flows at various Mach numbers over several surfaces will be built and analyzed in order to find correlations that are intended to inform system-scale CFD of hypersonic aerothermodynamics. Simulations will be run on the University of Southampton’s supercomputer Iridis 5.

You will have a PhD* or equivalent professional qualifications and experience in Aerospace Engineering / Mechanical Engineering / Applied Mathematics / Civil Engineering / Computer Science with specialisation in computational fluid dynamics and have experience of direct numerical simulation (DNS) and/or large eddy simulation (LES) for compressible high Reynolds number flows and/or supersonic aerothermodynamics. In addition you will have good programming background in C++ and Fortran as well as parallel high-performance computing experience in a Linux environment.  A publication record in computational fluid dynamics, specifically, large eddy simulation or direct numerical simulation of compressible flows is desirable.

This work is carried out in behalf of the Defense Science and Technology Laboratory (Dstl) and preference will be given to nationals of the UK, EU, US, Australia, Canada, New Zealand.

This post is fixed term until the 31st March 2022 due to funding restrictions.

We particularly encourage women, Black, Asian and minority ethnic (BAME), LGBT and disabled applicants to apply for this position. In recognition of our continued commitment to improving equality for women in science we were awarded an Athena SWAN bronze in 2013 and 2016.   We give full consideration to applicants that wish to work flexibly including part-time and due consideration will be given to applicants who have taken a career break. The University has a generous maternity policy**, onsite childcare facilities

The University of Southampton is in the top 1% of world universities and in the top 10 of the UK’s research-intensive universities. The University of Southampton is committed to sustainability and being a globally responsible university and has recently been awarded the Platinum EcoAward.  Our vision is to embed the principles of sustainability into all aspects of our individual and collective work, integrating sustainable development into our business planning, policy-making, and professional activities.  This commits all of our staff and students to take responsibility for managing their activities to minimise harm to the environment, whether this through switching off non-essential electrical equipment or using the recycling facilities.

*Applications will be considered from candidates who are working towards*** or nearing completion of a relevant PhD qualification. The title of Research Fellow will be applied upon completion of PhD. Prior to the qualification being awarded the title of Senior Research Assistant will be given.

**subject to qualifying criteria.

***Within six months of completion.
