Abstract:
The importance of creating a fluid flow with accurate and controllable flow in many industries is undeniable. There are several ways to create this type of flow, and a variety of pumps can be used to create such a flow. The presence of noise, limitations in reducing the flow rate (sometimes in some pumps the flow rate can not be reduced to a minimum), depreciation costs and many other limitations, reduce the attractiveness of using conventional pumps in some applications. The subject of this project is the design and construction of piezoelectric based micro-pumps to solve the above problems. In many applications, the need for fluid flow with very low flow and high quality and accuracy is essential, to meet this need, micro-pumps are generally used. Piezoelectric based micro-pumps are very small, light, inexpensive and fast response. Many active actuators, such as plasma, jet, etc., have been introduced for flow and boundary layer control in aerodynamic applications. Due to the mentioned features and at the same time, low energy consumption, piezoelectric based micro-pumps can be used for flow control applications by injecting secondary fluid with the desired frequency
