Outline of Final Research Achievements

A towing tank simulator has been developed based on CFD technique in order to evaluate the accuracy of tank tests and to extend the usability of towing tanks. An overset grid method is adopted in which a grid block represents a tank geometry and a grid block for a model ship are separately generated and overlapped and a tank test condition is reproduced. In addition, a body force based propeller model for self-propulsion simulations is extended to an overset grid method. Computations by the towing tank simulator show the reflection of ship waves on the tank walls and the so-called blockage effect to the resistance is analyzed. These results demonstrates the applicability of the towing tank simulator.
