Flow in the blood sac of the Korean artificial heart is numerically simulated by finite element method. Fluid‐structure interaction algorithm is employed to compute the three‐dimensional blood flow interacting with the sac material. For verification of the numerical method of fluid‐structure interaction, two‐dimensional flow in a collapsible channel with initial tension is simulated and the results are compared with numerical solutions from the literature. Incompressible viscous flow and linear elastic solid are assumed for the blood and the sac material in the device, respectively. The motion of the actuator is simplified by a time‐varying pressure boundary condition imposed on the outer surface of the sac. Numerical solutions on the unsteady three‐dimensional blood flow in the sac are provided for the cactus‐type model in this study. During systole, the inlet is closed and the blood sac is squeezed by the action of the …
