In Shipbuilding fields, there are strong demands for the CFD code which could simulate flow around a complex geometry, for example a marine propeller, perhaps the most complex shape among the parts of ship. In this paper, we discussed the way to simulate flow around a complex geometry with high-order accuracy. We solved the incompressible flow using artificial compressibility formulation. And High-order(>2nd order) solution is obtained by using a high-order solution reconstruction. We simulated various kind of simulations. And we showed the numerical results.
