摘　　要：论文针对水面船CFD标模KCS,进行CFD计算,模拟实船功率性能预报研究。比拟基于模型试验的水面船功率性能预报,开展了船模阻力、螺旋桨模型敞水和船模自航的数值模拟。通过对CFD模拟结果的分析,获得KCS实船的自航因子,并预报了设计航速下的实船功率。CFD计算模拟、分析及预报结果,都与模型试验及基于模型试验的预报结果进行了比较,总体上符合较好。CFD prediction of powering performance for a surface ship model KCS is carried out in this paper. Numerical computation of resistance for the ship model is performed firstly. Open water performance for propeller model KP505 is computed then： Numerical tests of self-propulsion of the ship model are carried out thirdly. Self-propulsion parameters are obtained through analyzing the results of CFD simulation. Powering performance of the full scale ship is predicted finally. It is shown that the results of numerical simulation and analysis agree quite well with the experimental results.
