Abstract

The ONERA-M6 test case based on the 1979 AR-138 AGARD Report has become an important and widely used validation case for transonic computational fluid dynamics simulations over a wing. It is also posted on NASA Turbulent Modeling Resource (TMR) website for evaluating the accuracy of various RANS turbulence models. Available wind tunnel pressure coefficient data allows for testing the ability of numerical methods and turbulence models to accurately simulate the formation of shock waves and shock/turbulent boundary layer interactions at 3.06 and 6.06 degree angles of attack. Flow separation occurs at the higher angle of attack of 6.06 degree. In this study, two turbulence models are employed to simulate the flow field over ONERA-M6 wing. The turbulence models considered are the one equation Spalart-Allmaras (SA) and the newly developed Wray-Agarwal (WA) model. Computations show that both turbulence models can simulate the flow field with good accuracy against the experimental data.
