Witryna关键词: 浸入边界法, 壁面模型, 扩散界面, 湍流, 不可压流动 Abstract: A diffuse-interface Immersed Boundary Method (IBM) for simulating high Reynolds number turbulent flows is proposed.This method uses the wall model to reduce the number of grids near the wall. To implement the wall model and boundary conditions, two auxiliary layers (a series … WitrynaIn computational fluid dynamics, the immersed boundary method originally referred to an approach developed by Charles Peskin in 1972 to simulate fluid-structure (fiber) interactions. Treating the coupling of the structure deformations and the fluid flow poses a number of challenging problems for numerical simulations (the elastic boundary …
