SES-71-179 PhD Studentship: 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. Because the project requires modifications to a research code, knowledge of FORTRAN and parallel computing will be an advantage.

Funding is for EU/UK fees levels only.  We regret it will not be possible to consider your application unless you can provide funding from other sources to pay the fees difference.
