| 摘 要： | 在浅水、薄船、无限宽水域的条件下,舰船以亚临界速度(F_H<1)运动时,利用E.O.Tuck提出的渐近匹配展开法,可以得到定深度扰动速度势的摄动方程。对水深缓慢变化的海底,舰船的绕流不再是定常的,根据A.Plotkin所采用的多重尺度法,可以得到变深度浅水舰船扰动速度势的摄动方程。如果仅考虑扰动速度势的一阶摄动方程,则可得到考虑了线性兴波影响的舰船水压场的计算公式。

| Abstract: | The Subcritical potential flows of a slender ship moving over a constant and slowly varying depth in wide shallow waters can be analyzed by the methods of matched asymptotic expansions and multiple scales,and the perturbation equations on constant and varying depth can be obtained. If the first order perturbation equations are considered only, the hydrodynamic pressure field of ship with the linearized ware effect can be simply given. |
