Numerical simulation of high lift trapezoidal wing configuration with WCNS-E-5 scheme
摘要
Abstract
High order accuracy numerical simulations for flows of high lift trapezoidal wing configuration were performed by solving Navier-Stokes equation together with SST two-equation turbulence model.In the study,WCNS-E-5 scheme was utilized in the discretization of convection terms,while 6 th order central differ-ence scheme for viscous term.Grid convergence result was obtained,which was in good agreement with test data,and WCNS scheme was less dependent on mesh density than 2 nd order scheme.Compared with other computational results obtained by typical CFD solvers,both the force coefficients and the surface pressure distributions given in this paper shown better accordance with the test data,and more reasonable prediction of flow structure near stalling was obtained.As revealed from these results,WCNS scheme took higher ac-curacy order and was more suitable for simulation of flow around high lift configurations than 2 nd order scheme.The capability and the robustness of the program to simulate complex high lift configurations were confirmed.关键词
