【摘要】 波－粘性流－海洋结构物相互作用的研究对海洋结构物附近地基的冲刷估计和防护是十分重要的．目前对这一问题的研究还不多．本文基于水深平均雷诺方程和水深平均ｋ－ε模型，对典型海洋结构物直立圆柱附近的粘性波流场进行了数值模拟．在数值计算中，应用了差分法、余量校正法和人工开边界条件．本文对雷诺数为１０５粘性流和正弦波联合作用时直立圆柱附近的波流场进行了计算．计算结果表明，本文方法对处理波－粘性流－海洋结构物相互作用问题是较为直接和有效的更多还原

【Abstract】 In this paper, a numerical model is presented for simulation of the flow field around a fixed vertical truncated circular cylinder subjected to waves and viscous currents based on the depth averaged Reynolds equations and depth averaged k ε turbulence model. Finite difference method with a suitable iteraction defect correction method and an artificial open boundary condition are adopted in the numerical process. Numerical results presented relate to the interactions of the co existing of viscous current with Reynolds 10 5 and regular sinusoidal wave with a circular cylinder. The present method is found to be relatively straight forward, computationally effective and numerically stable for treating the problem of interactions among waves, viscous currents and bodies.更多还原
