In this paper, it aims to understand blood flows and movements of the red blood cells (RBCs) in microcirculation, so the fluid-solid interactions numerical simulation of unsteady flows was conducted. The two-dimensional incompressible Navier-Stokes equations and equations of motion were solved simultaneously. The artificial compressibility method was used for solving the incompressible Navier-Stokes equations, and the overset method was used to accommodate the movement of the RBCs. A simulation of blood flows between parallel plates was carried out to reproduce blood flows in microcirculation. The results showed that rotation of the RBC was dependent on its initial position. And the wall shear stress was related to not only number of the RBCs but distance between RBC and the parallel plates wall.
