A Study on Fluid Flow Characteristic In a Microchannel

미세 유로에서의 유동 특성에 관한 연구

Fluid characteristics at microscale were tried to be solved in this paper by showing how they deviate with conventional flow governing equations. (e.g. Navier-Stokes Equation) In earlier studies, this deviation phenomena was caused because of omitting no slip flow condition, micropolar effect and EDL(Electric Double Layer)effect of fluid which are usually negligible at macroscaled phenomena. The characteristics of fluid flow were tried to be studied by measuring pressure difference of specified length of the channels using the almost squared micromachined channels. By acquiring pressure difference, we could drive different values (viscosity, flow velocity. etc) from it and these data will be compared with macroscaled flow characteristics. As making microchannel is not easy work and that our knowledge is at mere stage, we had to fail to make it in this time. The hardest thing in this work is to make a hole which is directly connected with channel. The more efficient and easy way of making microchannel is proposed in this paper.
