The immersed boundary method (IBM), first developed by Professor Peskin,¹ is a methodology for dealing with boundary conditions at interfaces (including fluid–fluid and fluid–solid ones) based on meshes that do not conform to the shapes of the immersed boundaries or interfaces. The advantages of the IBM are manifold: the mesh generation is very easy even for complicated geometries; mesh movement and mesh regeneration are avoided for flows involving moving boundaries and fluid–structure interactions (FSIs); it is easy to handle the cases where the topology of the computational domain changes; and thus the computational efficiency could be higher than that of the traditional body-conformal grid approaches for the cases involving complicated geometries and large boundary movement.^2–6 Due to its simplicity in mesh processing, the IBM has been attracting growing attention in the recent years with effort in developing new features and promoting its applications.^7–26

沉浸边界方法的最新趋势和进展

浸入边界方法（IBM）由Peskin教授首先开发[ ^1]，是一种基于不符合浸入边界形状的网格处理界面（包括流体-流体和流体-固体的界面）边界条件的方法。或接口。IBM的优点是多方面的：即使对于复杂的几何图形，网格的生成也非常容易。对于涉及移动边界和流固耦合（FSI）的流动，应避免网格运动和网格再生。计算域拓扑发生变化的情况很容易处理；因此，在几何形状复杂，边界运动较大的情况下，其计算效率可能会高于传统的人体保形网格方法。^2–6由于网格处理的简单性，近年来，IBM致力于开发新功能和推广其应用，从而引起了越来越多的关注。^7–26
