摘　　要：波浪破碎产生近岸流是近岸浅水区域一个重要的水动力现象。该文利用辐射应力的概念,并考虑辐射应力沿水深的变化、波浪破碎引起的水滚以及波流共同作用下的水底剪应力,建立了基于有限体积法的三维波生近岸流数值模型。运用建立的数值模型模拟了两个实验室实验,并同实验的实测结果进行了对比。结果表明,建立的数值模型能够较好地模拟波浪破碎产生的近岸流。Nearshore currents caused by wave breaking is a critical hydrodynamic phenomenon in nearshore coastal regions. Based on the finite volume method, considering the variation of radiation stress on the water depth, the surface roller induced by wave breaking and the bottom shear stress caused by the wave-current interaction, a three-dimensional nearshore wave-induced- current numerical model is established. The numerical model is applied to two laboratory experiments and the calculated results are compared with the experimental results. The numerical results show that the established numerical model can simulate nearshore currents induced by breaking waves effectively.
