摘要

In this paper, we describe an immersed boundary (IB)-lattice Boltzmann (LB) method for computing the fluid-structure interaction (FSI) encountered in biological and biomedical flows, such as fish swimming, red blood cell (RBC) dynamics and cell manipulating in micro scope. The approach combines a single relax time LB method for viscous incompressible flow and a delta function IB method for coupling the flexible boundary with the fluid. The IB method handles the effect of the moving boundary by spreading the stress exerted by the boundary on the fluid onto the collocated grid points near the boundary. For the boundary of FSI, the Lagrangian force is calculated by the standard second-order finite difference method, while the Lagrangian force of prescribed boundary is determined by a feedback scheme. The FSI solver has been validated and verified against previous studies. The details of this method and its applications in both fundamental study of biophysics of fish swimming, RBC behavior in micro flow and cell capturing in a micro architecture will be introduced.
