摘要
Abstract
First a formulation of immersed boundary method which uses a direct force to simulate the effects of solid boundaries on the flow is demonstrated in details.This method uses a bi-linear velocity interpolation and is embedded in a finite-volume solver.Then a preliminary study on large eddy simulation of the turbulent flow around an airfoil using the immersed boundary is presented,including the LES subgrid-scale stress modeling by SDP method based on the Germano identity and scale-similarity hypothesis.Simulation results agrees well with the published DNS data,which shows that the combination of SDP modeling with immersed boundary method produces an efficient and accurate solution of complicated turbulent flows.关键词
