摘要
将势流方法和CFD方法相结合的势粘流耦合方法,在船舶与海洋工程领域的波浪演化、波浪与结构物相互作用等问题中逐渐受到关注。势粘流耦合方法在保证计算精度的同时可以有效降低数值模拟的计算成本,使得实尺度的流固耦合精细模拟成为可能。本文对面向船舶与海洋工程水动力应用的势粘流耦合方法的发展和研究现状进行了总结,通过区域分解和方程分解两类耦合方法展开论述,分析其优势与面临的挑战。
The potential-viscous flow coupling method,which combines the potential flow method with the CFD method,has gradually attracted attention in solving issues of wave evolution and wave structure interac⁃tion in marine engineering field.The potential-viscous coupling method can effectively reduce the computa⁃tional cost of numerical simulation while ensuring the calculation accuracy,making it possible to achieve fine simulation of fluid-structure coupling on a real scale.In this paper,the state of art of the potential-viscous flow coupling method for marine engineering hydrodynamic applications are reviewed.Two types of coupling methods,domain decomposition and functional decomposition,are discussed to analyze advantages and chal⁃lenges of the coupling method.
