摘要：

In the planing of a high-speed boat, it is difficult to predict the complex geometry of spray and highly deformed free surface. The scale of spray is often larger than the length of the boat and its shape changes according to the speed and attitude of boat. In the situation, it is difficult to provide computational mesh with appropriate spatial resolution in both complex spray geometry and boundary layers around the hull. This paper presents a simulation procedure of the large spray formation around a high speed planing body. The method is based on Moving Particle Semi-implicit (MPS) method with modifications for ship hydrodynamics. They are surface tension, smooth body boundary, and efficient treatment of collision between free surfaces. The paper provides examples of two-dimensional falling wedge on the free surface and three-dimensional planing wedges. (C) 2013 Elsevier Ltd. All rights reserved.
