摘　　要：[目的]旨在解决传统Goldstein体积力法在导管螺旋桨水动力仿真中的适用局限性问题。[方法]首先,基于机翼理论,分析导管水动力模拟失真的原因,并以质量流量和体积力分布模型为切入点,提出修正思想和方法;然后,采用RANS方法探究经质量流量修正后的2种体积力分布模型的模拟精度。[结果]结果显示,2种改进体积力法在敞水工况下其总推力系数的平均相对误差均为5%左右;在艇后工况下,前进合力的平均相对误差分别为1.8%和11.6%。[结论]研究表明,基于改进体积力法的导管螺旋桨在敞水和艇后工况下的模拟精度较传统体积力法有较大的提升,能准确实现对导管螺旋桨水动力性能的数值模拟,可为水下航行器高效、动态的操纵性仿真奠定基础。[Objectives]The paper aims to solves the limitations of the Goldstein body force method in a hy-drodynamic simulation of a ducted propeller.[Methods]An analysis of the reason for the distortion of the duct hydrodynamic simulation is carried out based on the wing theory,and a correction method based on the mass flow and body force distribution model is proposed.The RANS method is then used to study the simula-tion accuracy of two kinds of improved body force method.[Results]The results show that the average rel-ative error of the total thrust coefficient of the two improved body force methods under open water conditions is about 5%.The average relative error of the resultant forward force of the two improved volume force meth-ods behind the underwater vehicle are 1.8%and 11.6%respectively.[Conclusions]The simulation accur-acy of a ducted propeller based on the improved body force method in open water and behind an underwater vehicle is greatly improved compared with the traditional method.The proposed method can accurately simu-late the hydrodynamic performance of a ducted propeller,laying the foundation for the efficient dynamic man-euverability simulation of underwater vehicles.
