摘要
船舶前进定常兴波对非定常水动力问题的影响,在物面边界条件中通过所谓的mj项体现出来。由于mj项含有定常兴波势的二阶导数,给实际计算带来困难。本文将边界元方法求解叠模流场mj项的技术进一步扩展到定常兴波流场mj项的计算。并以潜体为例给出计算结果。
To solve the unsteady ship motion problem, one has to consider the so called mj terms on the body surface condition. The technique based on BEM for double body flow mj terms is extended to solve the mj terms including the effects of steady waves. An example for submerged body is discussed.
