文摘

A higher-order finite volume method is developed for RANS simulations on unstructured meshes. A solution reconstruction strategy on curvilinear coordinates is devised for anisotropic meshes. The new reconstruction scheme highly improves solution accuracy. Higher-order discretizations deliver a more accurate solution with fewer degrees of freedom. Fast and efficient convergence to steady-state is obtained for higher-order methods.
