Reynolds Averaged Navier-Stokes (RANS) simulations and analysis of a trapezoidal three element high lift wing, using CFD++, is presented in this paper. Parametric study of grid and solver effect has been done. Requirements of the grid refinement at critical locations of the geometry are discussed. Optimized volume stretching ratio has been identified through the grid independent study. Simulations using various turbulence models available in CFD++ with various grids have been performed and results are documented. Predicted trends of lift coefficient (CL) and its maximum value (CLmax) are in close agreement with experimental data.
