| 摘 要： | 基于Nobleses新细长船兴波阻力理论,以匀速直航的定深椭球体为对象,运用新的数值计算方法,考察了物面分块数目、单元节点数目、波向角积分范围和特殊函数的项数对0阶和1阶兴波阻力数值计算结果的影响,并将计算结果与有关权威资料综合互校,证实这种算法对近水面潜体兴波阻力预报是可行的.

| Abstract: | Based on Noblesse's new sleder-ship theory of wave resistance,new numerical methods are used to calculate the wave resistance for submerged ellipsoid in constant depth and steady rectilinear motion beneath free surface,these influences of waterline integral term,the surface mesh number,element node number,range of the integration and truncation of special function expansions on zeroth-and 1st order numerical results of wave resistance were investigated.Comparisons with well-found numerical results were made,which prove the numerical methods in this paper can be used to calculate the wave resistance of submerged body near free surface. |
