Abstract

HPCMP CREATE™-AV Kestrel Components KCFD and COFFE are applied to computationally generate compressible flow-fields for the open source fighter at a variety of flight conditions. A series of high quality mixed element and fully tetrahedral P1 meshes were generated with the CREATE™-MG Capstone software. Flow solutions are calculated with both computational fluid dynamics solvers for the series of meshes at a “cruise” flight condition, and the coefficients of lift and drag are shown to minimally change for the mesh series at this flight condition for both KCFD and COFFE. This provides confidence in the solvers’ capability to compute accurate force coefficients with the “medium” mesh in the series, and flow solutions are calculated with both solvers on this mesh for more drastic “off-cruise” flight conditions. The “off-cruise” conditions include a wide variety of flight velocities and angles-of-attack, and both solvers produce similar integrated force coefficients and surface coefficient of pressure contours.
