摘　　要：基于RANS方法，融合VOF自由面捕捉、滑移网格及整体移动网格等多项技术，构建排水型船自航因子直接数值预报方法，通过对比KCS船体阻力试验值与计算结果，验证了数值方法的可行性，在此基础上开展了KCS船模在KP458螺旋桨推进下自航的直接数值模拟，计算结果表明，该方法可为船舶自航因子的快速预报提供强有力支撑。A mathematical model for self-propulsion of displacement type ship was developed based on Reynolds averaged Navier-Stokes and VOF equations. Sliding and integral dynamic mesh were applied to simulate propeller rotation and ship advan- cing respectively. The numerical method was verified with a good agreement with the simulation results and corresponding experimental data of KCS hydrodynamic performance. The direct numerical simulation of a self-propulsion of KCS equipped with KP458 propeller was carried out. The results showed that current method provides a feasible tool for rapidity forecast of surface ship.
