A pressure-based implicit finite-volume procedure to solve the Navier-Stocks equation with collocated finite volume formulation is used to simulate flow around the smart hydrofoil. The Volume of Fraction (VOF) method is applied for tracks the free surface. This simulation focuses two main goals. Initially, the equation of free surface wave due to moving submerge hydrofoil is extracted and the wavelength and amplitude of wave in different submerge distance (h/c) and angle of flap (AOF) are assessed. It is found, the trochoid equation predicts the free surface wave very well. Secondly, the simulation of fluid flow around the smart hydrofoil is performed and its results are compared with the conventional hydrofoil. For the both of hydrofoil types (smart and conventional), the effect of submerge distance and angle of flap are assessed. The results demonstrate that smart hydrofoils produce higher lift to drag ratio (L/D) than that of the conventional ones. Besides, the wave amplitude of smart hydrofoil is greater than conventional ones.
