报告题目：Numerical simulation of a flow impacted by metachronal coordination between beating cilia

摘要：In this paper we propose an effective approximation method for solving a mucociliary clearance model described by the volume-averaged Navier–Stokes equations with complex mix-boundary conditions and flow geometry interacted by the solid motion. The nonlinear terms are resolved using Chorin's projection that discretizes the temporal variable with semi-implicit scheme and decouples the system to several elliptic equations and Poisson-type equations. Then, the spatial variable is discretized by the finite element methods, and the numerical experiments show that the fully discrete scheme is effective with the convergence order  and ( ). We also give a biomedical simulation with non-negative stochastic inflow conditions generated by Brownian excursions, and the experiment indicates the effectivity, accuracy and stability of our scheme.
