Results from DoD HPCMP CREATE™ -AV kestrel for the 3^rd AIAA high lift prediction workshop

HPCMP CREATE™-AV Kestrel computational fluid dynamics (CFD) components KCFD, COFFE, and KCFD/SAMAir are applied to Tasks 1 – 3 of the 3^rd AIAA High Lift Prediction workshop. In task 1, a series of meshes for the NASA High-Lift Common Research Model were used to carry out flow-field versus mesh size studies at various angles of attack for all three CFD solvers. Mixed-element meshes were utilized in KCFD, P2 fully tetrahedral meshes were utilized in COFFE, and near-body (mixed-element)/off-body (Cartesian) meshes were utilized in KCFD/SAMAir. In Task 2, medium-fidelity meshes for the JAXA Standard Model with and without the nacelle/pylon were used to evaluate the accuracy of computed aerodynamic output as compared to experimental data for an angle of attack sweep. In Task 3, a series of P1 quadrilateral meshes was utilized for KCFD and COFFE to obtain the mesh convergence properties for a DSMA661 (MODEL A) airfoil at a fixed angle of attack, subsonic, high Reynolds number condition. A variety of turbulence models were employed for these computations, and all three CFD solvers demonstrated the capability to accurately predict the flowfield surrounding a commercial aircraft in a high-lift configuration.
