High-Order Wall-Modeled Large Eddy Simulation of High Lift Configurations

This paper presents several mesh and order refinement studies of the benchmark problems from the Fifth AIAA CFD High Lift Prediction Workshop (HLPW-5). A high-order large-eddy simulation (LES) solver, hpMusic, is used in the present study. Recent developments in wall-modeled LES and computing using graphical processing units have made such simulations for high-Reynolds-number problems feasible within a reasonable amount of time. The present study focuses on the high-lift version of the Common Research Model (CRM-HL) and pays special attention to the mesh and order sensitivity on the computational results. The study demonstrates a trend toward polynomial order [Formula: see text] convergent computational forces, pitching moment, velocity profile in the wall-normal direction, and surface flow topology. In addition, computational results are compared with experimental data when appropriate, which further validates the present methodology by correctly computing the maximum lift of the CRM-HL geometry. The study also assesses the capability of computational fluid dynamics to predict the effects of an increasing Reynolds number on the aerodynamic performance of the CRM-HL.
