非线性波浪在直立圆柱上爬高特性的数值模拟研究
Study of nonlinear wave run-up on a cylinder based on numerical simulation
摘要
Abstract
In ocean engineering,the interaction between waves and the interaction between waves and structures can cause extreme wave run-up phenomena on structures,which seriously threaten the safety of offshore engineering buildings.To understand the characteristics of wave run-up,a three-dimensional numerical wave tank was established based on non-hydrostatic numerical wave model,and the wave run-up of nonlinear waves on a small-diameter cylinder was studied.The results indicate that under the condition of limited water depth,after interactions between regular waves with varying wave steepness,scattering parameters,and wave depths,the distribution of liquid level height on the cylinder surface presents a similar trend,that is,the ratio of wave run-up height to wave amplitude increases with the increase of wave steepness and wave scattering parameters,and decreases with the increase of water depth,which can exceed twice the amplitude of the incident waves,resulting in extreme climb.In addition,as wave steepness increases,the maximum value of wave climbing speed at the wave-facing surface also increases,and the climbing height corresponding to the maximum climbing speed increases as well.关键词
