LES of Harrier a/c in ground effect demonstrated Parallel unstructured code converted from RANS mode Methodology validated against HGI-relevant test data Important unsteady phenomena observed in LES. e.g. influence of strakes/dams on ingestion process Simulations expensive but cost decreasing No other CFD technique offers sufficient fidelity of flow physics in ground effect flows to act as complementary tool to support rig test programmes.
