Validation of Numerical Schemes and Turbulence Models Combinations for Transient Flow Around Airfoil

Abstract

In the present study, combinations of turbulence models and numerical schemes are evaluated in terms of accuracy and computational cost for the prediction of transient flow at fixed points around the non-symmetrical ONERA-A airfoil for pre- and stall conditions using a finite volume method. The computed results were validated by experimental data. The purpose is to investigate whether TVD discretization schemes, developed initially for compressible flows, can help computation of incompressible flows when accuracy and low computational cost are important considerations, as in the case of aeroelastic calculations. The TVD discretization schemes are applied to the convection terms of the momentum equations and they are compared to central difference, upwind, hybrid and QUICK discretization schemes for several turbulence models. From the parametric studies, it comes out that TVD schemes can be a promising tool for aeroelastic calculations.
