Development of cartesian grid method for simulation of violent ship-wave interactions
We present a Cartesian grid method for numerical simulation of strongly nonlinear phenomena of ship-wave interactions.The CIP (Constraint Interpolation Profile) method1 is applied to the flow solver, which can efficiently increase the discretization accuracy on the moving boundaries for the Cartesian grid method.THINC (Tangent of Hyperbola for Interface Capturing)2 is implemented as the interface capturing scheme for calculation of free surface.An improved immersed boundary method is developed to treat moving bodies with complex-shaped geometries.In this paper, the main features and some recent improvements of the Cartesian grid method are described and several numerical simulation results are presented to discuss its performance.
