SIMULATION OF NONLINEAR SHIP FLOWS BY DENSITY-FUNCTION METHOD (2ND REPORT)

Following the first report (see abstract no 95040883), validation of the accuracy is made of a new computation method, WISDAM-VI, which employs the density function technique on the free surface, and two applications to practical hulls are made. The first isthe flow around a tanker model in ballast condition and it is revealed that the wave breaking motion causes momentum defect and that it interacts with the viscous flow forming a complicated wake. The second is flow around a high speed planing craft which involves highly nonlinear free-surface flow near the stern end.
