摘　　要：以DTMBP4119舰船螺旋桨为研究对象,基于求解RANS方程的STAR-CCM+流体软件,采用滑移网格、多重参考系模型,进行非定常的敞水性能、定常的敞水性能的数值模拟。两种数值计算均与试验值具有较好的一致性;但采用滑移网格的非定常计算结果相比采用多重参考系模型更加接近试验值,表明滑移网格技术具有更高的计算精度,更加适用于数值模拟舰船螺旋桨的特殊性能。In order to develop more accurate and suitable for viscous flow field numerical simulation calculation method of ship propeller,the DTMB P4119 propeller was as the research object.Based on RANS equation of STAR-CCM+fluid software,using sliding mesh(SM),multiple reference frame(MRF)model,respectively for the unsteady open water performance,steady numerical simulation of open water performance.The numerical results of the two methods are in good agreement with the experimental results.However,compared with MRF model,the unsteady calculation result of sliding mesh is closer to the experimental value,which indicates that sliding mesh technology has higher calculation accuracy and is more suitable for numerical simulation of special hydrodynamic performance of propeller.
