Abstract
Micro-fluidic devices and their applications have received a lot of attention in recent years due to the fast growing progress in the field of Micro-fluid systems. Micropumps are one of the most important micro-fluidic components. In this work, a 2D simulation, using Computerized Fluid Dynamic CFD software, is performed to study the fluid coupling effect driven by piezoelectric actuation of a valveless micropump. The results show the relationship between inlet velocity, actuation value, the flow velocity and pressure inside the valveless micropump using laminar and turbulent models solutions.
