均匀流中双色波传播特性的模拟研究
Numerical study on propagation characteristics of bichromatic waves in uniform current
摘要
Abstract
As for the problem of bichromatic waves interaction with uniform current ,the time-domain higher-order boundary element method is used to found a numerical model satisfied the fully nonlinear free surface boundary conditions .In the solving process ,the mixed Eulerian-Lagrangian method is adopt-ed to track the transient water surface and the 4th Runga-Kutta technique is used to refresh the velocity potential and free surface at the next time step .By comparison with the published experimental results , the proposed model is validated .Numerical experiments are performed to study the rules for the effects of current velocity on various composition wave amplitudes and power exchange between bichromatic waves and current .关键词
