| 摘 要： | 船舶浅水水动力导数对研究浅水中船舶操纵性有重要的意义.以“Mariner”船模为研究对象,采用Realiz-ablek-ε湍流模型来封闭RANS方程,运用SIMPLE算法,对两种水深的浅水定漂角、定舵角、纯艏摇试验进行了数值模拟.实现了浅水水动力导数的求取,并将计算结果与模型试验结果进行对比,验证了方法的有效性.

| Abstract: | Hydrodynamic derivatives of ships in shallow water are essential for studying ship maneuverability in shallow water.Taking the ship model Mariner as the studying object,this paper carries out a series of numerical simulation under static drift,static rudder and pure yaw in two different water depths by solving the Reynolds-average N-S equations with Realizable turbulence model using SIMPLE algorithm.The numerical results are compared with experimental results and calculated results published in literature t... |
