On the basis of Fluent software, Renormalization Group (RNG) k - ε model, Volume of Fluid (VOF) method and dynamic meshes are employed to simulate wave and current motions on circular duct. The computational results including surface height, velocities, pressure and force are obtained and analyzed. Computational drag force (CDF) coefficient, computational lift force (CLF) coefficient and computational composite force (CCF) coefficient on the circular duct vary periodically in coincidence with the wave period. It is the wave that causes the periodic changes of CDF, CLF and CCF. The absolute value of CLF is greater than CDF. CLF is the main factor that determines CCF when the circular duct is close to the wall. © 2010 World Scientific Publishing Co. Pte. Ltd.
