Abstract
Wall-Modeled Large Eddy Simulation (WMLES) is an area of interest due to its ability to lower computational costs of LES. Even with the application of wall models, LES still proves to have practicality issues when it comes to use in industry, due to the expertise, time, and computational resources required. A novel technique for generating a lean, physics based WMLES grid is described.
The technique utilizes a RANS solution to extract turbulence information, user-specified values related to resolution of turbulent energy levels, acoustics waves, and shock waves, to generate a point cloud for producing a lean WMLES grid with in-house solver, Eagle3D. WMLES solutions for the NASA transonic bump case are calculated using auto-generated grids and compared to existing highly-resolved WRLES results and experimental data for wall pressure and friction distributions, turbulent boundary layer profiles, and spectral analysis. A preliminary exploration of the sensitivity of results to the physics-based settings is considered. Artificial turbulence generation with mesh coarsening is thoroughly investigated.
