摘　　要：基于RANS方程,文章采用k-εSST湍流模型和VOF两相流模型,对一条圆舭艇进行数值模拟,研究了尾板安装角度对圆舭艇总阻力的影响。将软件数值模拟结果与船模试验值进行对比。研究结果表明,通过CFD软件可预报圆舭艇的水动力性能,改变圆舭艇尾部压力分布是尾板产生减阻效果的主要原因。The numerical simulation for round bilge displacement craft is based on RNG k-ε SST model and VOF method,and the influence of different installed angle of stern flap for total resistance is studied.The calculation results are compared with ship model experimental results.The results show that it's available to simulate and predict the resistance of hydrodynamics of round bilge displacement craft by CFD,and stern flap will change the pressure distribution of the after body of the ship hull,which is the main mechanism of reduction of resistance.
