| 摘 要： | 对于无限水深非定常不可压缩粘性流体，计入非线性自由表面边界条件的船体绕流，根据薄边界层理论和Ｐｏｉｓｓｏｎ压力方程，应用有限差分数值方法，计算绕船体流场参数及其阻力。以ＳＳＰＡ７２０模型进行了考核；其结果表明同有关计算方法具有相同的精度量级，可作为低雷诺数下流场计算的数学模型和数值方法。

| Abstract: | For an unsteady incompressible fluid with nonlinear free surface condition and with infinite water depth the Navier-Stokes equations and the additional Poisson equation are applied to determine the viscous flow parameters around ship hulls and to calculate the viscous resistance. SSPA 7 2 0 model is used to examine this computation and the corresponding results show that both mathematical model and numerical method are qualitatively reasonable only at low Reynolds number. |
