| 摘 要： | 提出一种基于SIMPLE算法的非定常流固耦合计算方法。流体Navier-Stokes方程空间采用非结构化网格有限体积法离散,时间项采用了欧拉隐式方法。利用浸入式边界方法模拟静止或者运动固体区域,流固界面作用力通过流体体积(VOF)方法进行处理。从而可以用固定网格求解任意复杂区域中的流固耦合作用。本文模拟了低雷诺数静止及振荡圆柱绕流,所得结果与文献中贴体网格计算结果吻合,从而验证了本文方法的合理性和正确性。

| Abstract: | This article introduces a numerical scheme on the basis of semi-implicit method for pressure-linked equations(SIMPLE) algorithm to simulate incompressible unsteady flows with fluid-structure interaction.The Navier-Stokes equation is discretized spatially with collocated finite volume method and Eulerian implicit method in time domain.The hybrid method that combines immersed boundary method(IBM) and volume of fluid(VOF) method is used to deal with rigid body motion in fluid domain.The details of movement of ... |
