基于RANS方法的波流耦合数学模型
Numerical Simulation of Wave-Current Interaction Using a RANS Solve
摘要
Abstract
This study developed a numerical model which was based on the Reynolds-Averafed Navier-Stokes( RANS)equations with k-ε turbu-lence closure scheme for the investifation of wave propafation in the presence of a steady current. To capture the water-air interface,the volume of fluid( VOF)method was adopted in the model. The steady current was fenerated by providinf a steady inlet velocity at inlet boundary and pressure outflow at outlet boundary,while the wave was fenerated by an internal mass wave-maker. Simulated water elevation and velocity distribution a-freed well with the well-documented laboratory measurements,showinf this model had a freat ability in modelinf wave-current interaction. The nu-merical result indicates that the wave period and current velocity have sifnificant impacts on the water surface and velocity distribution induced by the interaction of wave-current.关键词
