Within the framework of high-order discontinuous finite elements (DFE) methods, the objective of this project is the development of advanced modeling strategies for Large-Eddy Simulation (LES) of transitional turbulent flows over complex geometries. DFE methods allow to perform the numerical simulation of turbulent confined flows preserving numerical accuracy regardless of the mesh and the geometry. Specific efforts will be done to develop dynamic coupling strategies between a detailed description of Reynolds Averaged Navier-Stokes (RANS) turbulent boundary layers (BLs) and LES. The final goal of the proposed research is the development of highly accurate hybrid RANS-LES wall modeling approaches for transitional BLs and/or turbulent BLs with variable mixing layer thickness.

Research program

The proposed research is mainly focused on the development of modeling strategies to perform high-fidelity LES computations of transitional turbulent flows over complex geometries. At the core of these activities is the ongoing development of an MPI parallelized fortran 90 numerical solver for compressible flows based on the DFE method, namely, the high-order Spectral Difference (SD) scheme.

A 12 months postdoctoral appointment will be available starting early 2017 and the relevant envisaged activities will be : • perform reference LES computations of transitional BLs ; • develop advanced hybrid RANS-LES modeling strategies to handle transitional turbulence ; • extensively validate the developed modeling strategies.

Candidate profile

The candidate should hold a PhD degree in Engineering (Aeronautical, Mechanical), Physics, Applied Mathematics or related fields and have a significant experience in the development and implementation of numerical algorithms for Computational Fluid Dynamics with particular emphasis on applications to LES over massively parallel environments. A good proficiency with the Fortran language is desired. Prior experience with DFE methods such as Nodal Discontinuous Galerkin, SD or Flux Reconstruction will be highly appreciated.
