The fifth-order accurate explicit HWCNS(hybrid cell-edge and cell-node weighted compact nonlinear schemes) was used to solve Reynolds averaged NavierStokes equations. The grid convergence study of 30P-30N was performed by generating multi-block structured grids. The effects of HWCNS and the secondorder accurate MUSCL on pressure distribution and velocity profiles at typical stations were studied using SA turbulence model without regarding transition, furthermore the numerical and experimental results were compared and analyzed. The trapezoidal wing was numerically simulated using HWCNS and SA turbulence model, and the application performance of HWCNS for low-speed complex configuration flows was discussed by analyzing the aerodynamic characters and the pressure distribution.Simulation results indicate that the pressure distribution of 30P-30N is simulated with the fully turbulent model accurately; as for the trapezoidal wing, HWCNS shows good simulation performance when dealing with the attached flow and small flow separation.
