The cavitating flow simulation is of practical importance for many engineering systems, such as pump, turbine, nozzle, injector, etc. In the present work, a solver for two-phase flows has been developed and applied to simulate the cavitating flows past hydrofoils. An experimental data and other numerical data were compared with the present results to validate the present solver. It is concluded that the present numerical code has successfully accounted for two-phase Navier-Stokes model of cavitation flow. This study could be confirmed chracteristic of hydrodynamic coefficients with change of the angle of attack. Lift and Drag coefficient increase as the increase of angle of attack. When hydrofoil is pitching motion, lift coefficient of hydrofoil for upstroke and downstroke is not changed to the decreases of cavitation number.
