%X this work shows a computational approach to simulate blood flowing through an aortic mechanical heart valve by cellular automata theory. a lagrange fluid-structure coupling is considered in this approach and changes in the fluid£¿s properties by the opening/closing of the leaflets during heart cycle£¿s time steps. velocities and shear stresses profiles in blood£¿s flow when it passes through the mechanical device were studied and discussed. numeric results of systolic cardiac phase were obtained. qualitative streamline maps are showed, with similar results of in vitro tests published by lim et al. (1998).
