摘　　要：以某型集装箱船为研究对象,使用PARNASSOS软件进行了船后伴流场影响因素的数值研究.采用GMS软件为前处理器,采用NAPA软件的Transformation模块进行线型变换,并将所建模型导入PARNASSOS进行伴流场的计算;计算结果与实验值比较,验证了该方法的有效性.在此基础上,以平均伴流和伴流目标函数(WOF)作为计算结果的衡量标准,依次研究了方形系数、尾部U,V度、船体长宽比、航速和桨盘面位置等对伴流场的影响.Taking a container ship as example,numerical study on the factors affecting the wake field behind ship is carried out.The software GMS is used as pre-processor to create the models and modifications are made with the transformation module of NAPA.Then the models are imported into the software PARNASSOS to calculate the wake fields.The numerical method is verified by comparing the calculation result with experimental result.On this basis,with Mean Wake Fraction and Wake Object Function （WOF） as measurement,the influences of block coefficient,U,V degree of stern form,ratio of length to breadth of the hull,ship speed and position of propeller on the wake field are investigated.
