基于二阶完全非线性Boussinesq方程的波生流模拟
Modeling Wave-induced Currents Based on Boussinesq Equation
首次将Kennedy的紊动模型引入一组色散性达到Padé(4,4)的二阶完全非线性Boussinesq方程中，建立了基于完全非线性Boussinesq方程的波生流数学模型。基于有限差分法在交错网格体系下对数学模型进行了数值离散,采用该模型对波浪破碎产成的沿岸流和沙坝地形上的近岸流进行了数值模拟分析。数值模拟结果表明，该模型可以有效的模拟波浪破碎产生的近岸流。
he 2-D model for wave-induced current was derived. The model was based on the second-order fully non-linear Boussinesq equation with dispersivity of Padé(4,4), and the wave breaking effects was considered by introduced the term in Kennedy's model. The mathematical model was discretized using finite difference method in non-staggered grid system. The breaking wave induced longshore currents and nearshore currents on sandbar were modeled and analized by the present model. The numerical results showed that presented model is an effect tool for simulating the breaking wave induced near-shore currents.
