متن کاملModeling Valveless Pumping Mechanisms
Austin J Baird: Modeling valveless pumping mechanisms (Under the direction of Laura Miller) Several mechanisms of valveless pumping are studied numerically. The discussion begins with an introduction into the two well-known driving mechanisms of flow in valveless tubes: impedance pumping and peristalsis. Flow generated from peristalsis and impedance pumping is examined using the immersed bounda...
متن کاملEquivalent Circuit Model for Square Ring Slot Frequency Selective Surface
An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...
متن کاملA valveless micro impedance pump driven by electromagnetic actuation
Over the past two decades, a variety of micropumps have been explored for various applications in microfluidics such as control of picoand nanoliter flows for drug delivery as well as chemical mixing and analysis. We present the fabrication and preliminary experimental studies of flow performance on the micro impedance pump, a previously unexplored method of pumping fluid on the microscale. The...
متن کاملDesign and Simulation of A Piezoelectric Actuated Valveless Micropump
In this work, we design and simulate a valve less, diaphragm-based, piezoelectric micro pump. The piezoelectric actuator is a PZT-5H piezo-disk, the diaphragm is a borosilicate glass plate. All the simulations were made using COMSOL Multiphysics software. First, the piezoelectric actuator and membrane thicknesses were chosen by means of a stationary simulation, using the piezoelectric devices m...
