Based on Computational Fluid Dynamics (CFD) technique, the numerical simulation of T-hydrofoil was studied. The flow around the 2D hydrofoil was simulated by the modified RNG k-1 two-equation turbulence model. The lift coefficient, drag coefficient, lift-drag ratio and pitching moment coefficient of common hydrofoil and hydroflap on different working conditions were calculated and compared with experimental values after comprehensive analysis. The variation law of hydrodynamic coefficients with attack angle and flap angle were concluded by computing results, which provided basis in the application of trimaran.
