High Order Finite Volume Schemes for Numerical Solution of Unsteady Flows
Original language description
The aim of this contribution is to present two modern high-order finite volume (FVM) schemes for numerical solution of unsteady transonic flows. The first one is derived from the total variation diminishing (TVD) version of the classical MacCormack scheme proposed by Causon. The second one, based on a similar approach as the WENO family schemes, is the implicit Weighted Least-Square Reconstruction scheme (WLSQR) used in combination with the AUSMPW+ numerical flux. For the turbulence modeling the Kok's TNT turbulence model is employed. Unsteady effects (forced oscillatory motion) are simulated by Arbitrary Lagrangian-Eulerian method (ALE). As the transonic test cases the inviscid and turbulent flow around the NACA 0012 profile and inviscid flow over theONERA M6 wing were chosen. Comparison of numerical and experimental results for inviscid flow is very good, which is unfortunately not the case of turbulent flow.
