Postdoctoral Research Fellow in Eddy-resolving Simulations for Turbomachinery Applications

Traditionally, the design of turbomachinery components has been exclusively accomplished with steady CFD, with Reynolds Averaged Navier-Stokes (RANS) models being the predominant choice. With computing power continuously increasing, high-fidelity numerical simulations of turbomachinery components are now becoming a valuable research tool for validating the design process and continued development of design tool.
 
In the current project, Direct Numerical Simulations (DNS) and other eddy-resolving approaches will be performed of turbomachinery components to establish benchmark data for design tools, and to investigate physical mechanisms that cannot be captured by traditional CFD approaches.
 
The primary research tool will be an in-house compressible Navier-Stokes solver which is currently used for DNS of axisymmetric flows (e.g. round jets) on UK national supercomputers and the University of Southampton research cluster, running on thousands of computing cores.

The DNS data will serve as benchmark data for other turbulence simulation approaches with reduced computational cost, such as large-eddy simulation (LES) or hybrid RANS/LES methods.
 
The Faculty of Engineering and the Environment brings together a range of inter-related disciplines and sectors, including acoustical, aerospace, biomedical, civil, computational, electro-mechanical, environmental, mechanical and materials engineering, energy technologies, ship science and transportation with world class strength in depth.  It is one of the largest and highest rated such grouping in Europe.

The Faculty has an overall income of around £57M p.a., almost 65% of which is from research and commercialisation activity. It represents a community of 1,560 undergraduate, 300 taught postgraduate and 370 research postgraduate students.

There has been a 24% growth in students and a 21% growth in research funding over the past three years. The Faculty comprises some 340 academic and 140 other staff.
 
Entry requirements: Candidates will have completed their PhD in relevant disciplines, e.g. aeronautical/mechanical engineering, applied mathematics, physics. Because the project requires modifications to a research code, knowledge of FORTRAN and high-performance computing will be essential.
 
The successful candidate will work with a group of highly motivated, first class research students and researchers in the areas of aerodynamics, aeroacoustics, fluid dynamics.

Closing Date:   Wednesday 30 November 2011
