Abstract
In this paper, we propose a valveless micropump with an improved inlet/outlet channel configuration for biomedical applications. To do so, we added curved parts known as "ears" to a standard diffuser/nozzle shape. This new design will enlarge the flow rate values between both directions for the purpose of improving the valveless micropump efficiency. After that, the new channel is incorporated into a double valveless micropump superimposed on each other making the diaphragm in sandwich. This kind of micropump shows no reflux at its common outlet and good reliability due to the new design of the diffuser/nozzle channel. COMSOL Multiphysics software is used to model and simulate, under Fluid-Structure Interaction (FSI) physic, the complete system of the superimposed valveless micropump (SVM). The results are promising and show that our kind of micropump is necessary for medication injection because of the no backflow at its common outlet, and also because of the increase in its efficiency.
