The present paper contributes to the development of an efficient numerical solver for studying BZT fluid flows in general geometries. An efficient 3D extension of an unstructured solver for dense gas flows is developed. It includes a quadratic least-square-based reconstruction ensuring 3rd-order accuracy on general grids and low-Mach preconditioning to speed up convergence in low-speed regions. Applications are represented by inviscid BZT flows over the ONERA M6 wing.

Abstract
The present paper contributes to the development of an efficient numerical solver for studying BZT fluid flows in general geometries. An efficient 3D extension of an unstructured solver for dense gas flows is developed. It includes a quadratic least-square-based reconstruction ensuring 3rd-order accuracy on general grids and low-Mach preconditioning to speed up convergence in low-speed regions. Applications are represented by inviscid BZT flows over the ONERA M6 wing.File in questo prodotto:
