Fabrication and Performance Analysis of Hybrid Configuration Micro-Mixers

Abstract

Mostly the micro channel parts are significant for lab on a chip device. Use of micro mixers is in biomedical devices and micro fluidic applications. The fabrication of micro mixers is quite tough by using conventional manufacturing. To characterize technology, different methods are used for the fabrication of micro channel. By using both conventional and non-conventional techniques, like micro milling, lithography, embossing processes and laser ablation processing. In the present days, Acrylic comes in a wide variety of standard. The fact that some of them are bullet resistant, it is now in highly demand. Acrylics come in various shapes. There are many ways of processing them, and the one discussed here is the process done by using laser cutter machines. The process is called laser-cutting process. In this paper, a study on the use of a commercial CO2 laser system for fabrication of micro-channel moulds using acrylic material. The accuracy of micro mixer mainly depends on the fabricated moulds. By using laser power and scanning speed we can control the depth of micro channel. To analyse the effect of Laser power and scanning speed on the depth of the Micro mixers mould primary experimentation is performed. According to analysis, it is observed that the depth of micro mixer mould increasing linearly with an increase in laser power and decreasing with increasing speed. The Y shape micro mixers hybrid configurations are designed and their experimental and numerical analysis is carried out using COMSOL Multiphysics software.
