A mathematical model of a sac-type artificial ventricle is presented. The model, derived from the mass conservation and energy equations of a deformable control volume, is used in a digital simulation study of a latex ventricle in mock circulation. The hinged disk valves mounted within the ventricle are modelled as nonlinear resistive elements with flow regurgitation. The simulation results are compared with experimental measurements.
