源汇分布法求解非对称剖面水动力系数
After solution of radiational and diffractional fluid field of asymmetrical sections by applying the multipole expansion method , wave loads on damaged ships are calculated by the linear strip theory under the non - upright floating condition , taking the effect on the heel angle and trimming angle caused by the damaged tank inundation below waterline into account
然后采用线性切片理论，计及水线以下破损后船舶由于舱室进水产生的横倾角与纵倾角的影响，利用多级展开法求解非对称剖面的二维辐射和绕射流场，计算了破损船体非正浮状态条件下的波浪载荷。
Secondly , proportional arc length method is used to conformal mapping process of asymmetry sections so as to solute the 2d radiation problem with the method of multipole expansion . on the basis of above , 3d hydrodynamic coefficients are given and motions of the container ship flokstra are predicted considering the initial heel
然后，采用比例弧法对全剖面进行保角变换并在此基础上用多极展开法计算非对称剖面的辐射流场，进而采用切片理论合成全船的水动力系数并对flokstra集装箱船进行了考虑横倾影响的运动响应预报。
