A hydrofoil with a winglike structure is used underneath water surface as shown in Figure 4b (i) to create sufficient lift to the boat hull and reduce the hull drag resulting to increase in fuel efficiency. The shape of the hydrofoil is shown in Figure 4b (ii). The boat is moving towards the negative x-direction at a constant velocity of 15m/s. In order to investigate the hydrodynamics in the radius of 0.5m around the hydrofoit, you are required to perform a two-dimensional CFD simulation. Assuming that there is no variation of velocity in z-directions, sketch the CFD computational domain and your mesh structure, and state the boundary condition of the simulation. Explain your answers.
