摘要
本文为非传播孤立波建立了两种数学模型:一是考虑表面张力影响的势流模型,并得到了关于垂直激振和水平激振稳态解的近似解析表达式,与实验观测现象较为吻合;二是考虑表面张力以及粘性影响的非惯性系水柱模型,在垂直激振情况下,有限差分数值结果也与实验数据相近.
Two mathematical models for non-propergating waves are establi-
shed.The first one is a potential flow model,which considers the effect of
surface tension and leads to some analytical expressions of atatic solution in
both vertical and horizontal excitations.The second one is a water cylinder
model in a non-inertial system with the effects of surface tension as well as
viscosity.A mixed spectral-difference method gives good numerical results
coinciding with the experimental.
