Article Preview

Numerical maneuvering tank (NMT) is developed which could be used for investigating the flow physics involving the interaction of the flow shed from the sail and the cross-flow boundary layer of the hull, interaction between the hull and appendages like rudder and propeller during maneuvering operation. Two numerical codes are used for this study: CADMV (computer aid design of marine vehicle) and FLUENT commercial code. They are validated against each other and compared with experimental measurement results. Pressure coefficient and skin friction coefficient are obtained and compared with experimental data available in the literature. The simulation results show good agreement with the experimental data. NMT was developed based on above numerical method to simulate the circular motion of marine vehicle. The steady, uniform flow fields are obtained and the characteristics of rotation flow show good agreement with actual phenomena. The circular motion simulations of a SUBOFF in NMT is conducted at different angle of drifts of hull. The obtaining of hydrodynamics parameters is very important for accurately predicting the hydrodynamic behavior of a maneuvering marine vehicle in turning motion.
