摘　　要：本文总结了浸入式边界方法(immersed bundary method,IB method)中的力源建模研究进展,并且对该方法在诸如生物体绕流及流固耦合等典型的复杂边界以及运动边界问题中的应用进行了介绍.边界精度低是IB方法主要特征之一,但该方法目前在计算气动声学等高精度计算中同样有所应用.最后本文对IB方法在处理高雷诺数流动问题上所面临的挑战以及目前研究进展和未来发展方向进行了介绍.This paper summarizes the advances in the modelling of force source for the immersed boundary(IB)method.Introductions have been given to the applications of this method in the fields of flow around biological structures and fluid-structure interaction,which are representatives of problems with complex and moving geometries,respectively.Although low accuracy at boundary is one main feature of the IB method,it has also been applied to these computational aeroacoustic problems which requires high-order accuracy.Finally,the challenges,advances and future expects of the IB method in dealing with high-Reynolds-number flow are also reviewed.
