Abstract:

A three-dimensional boundary-layer computer program is developed which is suitable for application to arbitrary ship hulls. The program embodies the Wilcox-Rubesin two-equation model of turbulence. The numerical algorithm, based on the Blottner variable-grid method and the Krause explicit marching technique, is tested for two ship hulls and found to be accurate and stable for relatively large reverse crossflow. The program admits rapid stretching of the grid normal to the surface and solution become grid independent for mesh-point number in excess of about 60.
