—A planar peristaltic pumping device is studied in the scope of CPU cooling. The wall shape of the channel is imposed by a set of actuators. The purpose is to study the most appropriate driving conditions in order to optimize the coolant flow rate. Among several parameters such as frequency, wave amplitude or position and size of actuators, the phase shift of actuator supply are particularly studied. The theoretical analysis of the flow rate is performed with a simplified computational model. To validate this approach, results are compared to 3D CFD numerical simulations. In some specific operating conditions, it is demonstrated that the simplified approach allows to identifying the appropriate driving conditions.
