Abstract

The high-lift JAXA Standard Model (HL-JSM) has been numerically analyzed in order to further validate the HEMLAB code for realistic aircraft configurations. The numerical algorithm is based on highly efficient edge-based data structure for a vertex based finite volume algorithm on hybrid meshes. The data pattern is arranged to meet the requirements of a vertex based finite volume algorithm by considering data access patterns and cache efficiency. A fully implicit version of the numerical algorithm has also been implemented based on the PETSc library in order to improve the robustness of the algorithm. The resulting algebraic equations including the one-equation Spalart-Allmaras are solved in a monolithic manner using the restricted additive Schwarz preconditioner combined with the FGMRES(m) Krylov subspace algorithm. The numerical method is also combined with the metric based anisotropic mesh refinement library PYAMG in order to improve the numerical accuracy. The numerical algorithm is initially applied to the two dimensional L1T2 (NHLP) high lift system and then the calculations around the high-lift JAXA Standard Model are carried out at relatively high angle of attacks. The numerical results with the anisotropic mesh refinement library PYAMG indicate significant improvements in numerical accuracy.
