T型微通道内流体流动的FLUENT模拟

FLUENT simulation of fluid flow in a T-junction Microchannel

在流体力学研究中,微流控技术是当今研究的一个热点。利用微尺度下流体流动的一些特性可以提高流体间传质、传热以及反应速率。T型微通道是一个比较常见的微流控装置,利用ICEM CFD软件建立T型微通道的几何模型;然后通过FLUENT软件对微通道内流体流动进行模拟仿真。模拟实验结果表明,通道内两相流体的速度和粘度对流型有显著影响。

Microfluidies is widely used in fluid mechanics research.Some eharaeteristics of fluid flow in nlierosale ean improve the heat transfer and reaelion rate of fluid.T-junction Mieroehannel is a eommon microfluidic device.In this article, Using ICEM CFD software, a geometric model of T-junction Mieroehannel is established.And the fluid flow is simulated by FLUENT.The simulation resuhs show that the veloeity and viscosity of two phases has significant effect on the flow panern in mieroehannel.
