Abstract

Abstract:

Based on the Reynolds-averaged Navier-Stokes(RANS) equations and structured grid technology, the fifth-order weighted compact nonlinear scheme(WCNS) and shear stress transport(SST) turbulence model are adopted to simulate DLR-F6 wing-body and FX2B fairing configuration from the third AIAA CFD drag prediction workshop. The main purpose of the present work is to further validate the ability of WCNS in the simulation of transonic problems and the prediction of aerodynamic characteristic variation due to tiny variation of the configuration. The grid convergence study is performed with coarse, medium and fine grid systems at fixed lift coefficient, and the effects of grid density on the simulation of DLR-F6 with and without FX2B fairing are studied from the aspects of aerodynamic coefficients, pressure distribution and flow pattern on the surface. The variations of aerodynamic characteristics with angles of attack are performed with the medium grid system. Compared to the experimental data from the National Transonic Facility(NTF)and CFL3D numerical results, the numerical simulation indicate that grid convergence results are obtained with the high-order numerical method; the small incremental aerodynamic characteristics and the local flow difference at the wing-body junction with and without FX2B fairing can be predicted reasonably.

Key words: RANS equations, WCNS, flow simulation, grid density, aerodynamic characteristics
