Abstract
Free surface behavior is a common phenomenon in the nature. It combines spray creation, large deformation and breakup of water. Due to its unfixed computational boundary, the boundary position needs to be solved as a portion of result. However, it is a challenge to give sufficient spatial resolutions al ong the time-dependently changing free surface. In this pap er, a mesh free method, moving null semi-implicit method (MPS), based on the particle mechanics will be used and applied to analyze the phenomena of a ship with partially filled tanks rolling in regular waves. Th ereby, not only the external flow around the hull but also the free surface flow inside partially filled tanks can be simulated together by using a single algorithm base d on this method. The influences of the sloshing effect resulted from the free surface flow to the rolling of a ship will be discussed in this paper. Some case studies will be chosen for demonstrating results thanks to the advantage of this method.
