摘要
本文把陈耀松等人用自由面和物面分布偶极子求解二维物体瞬态水动过程的思想推广到三维物体的水动过程计算,物面代之以源汇分布。作为应用,数值模拟了圆球和回转体运动时的水动力及其产生的波浪,计算结果与PMM拘束模型试验结果和其他学者的数值计算结果进行了比较,结果令人满意。
This paper extends Chen Yao-song's method for solving the transient wave propagation caused by a two-dimensional body to a three-dimensional body. The motion can be of large amplitude, and the free surface condition is linear. The total flow is simulated by the distribution of dipoles on free surface and sources on body surface.The hydrodynamic process from transient to steady state of a 3-D body is studied. As an application of the method, the wavemaking of a sphere and a revolution-body is calculated. The calculated coefficients of lifting forces and resistances show good agreement with those measured by PMM captive model tests or computed by others.
