1 ResultProject Description This project aims to conduct computational fluid dynamics (CFD) simulation for a small catamaran unmanned surface vehicle (USV) to predict its calm water resistance and analyze its hydrodynamic performance. The research object is a 0.9-meter-long round-bilge catamaran hull with a design speed of 1.2 m/s. A steady-state incompressible flow model with the standard k-epsilon turbulence model is adopted to simulate the external flow around the hull. This simulation will calculate the total hull resistance, visualize the hull surface pressure distribution and stern wake flow field. The numerical results will be compared with the empirical resistance values calculated by the NPL series chart method to verify the rationality of the hull form design.
