Flow Characteristics of Fluids in a Microchannel Driven by Hydrostatic Pressure
静压驱动下微流体的流动特性

Based on the fabrication process of a microchannel,a method to measure the flow characteristics of fluids in a microchannel driven by hydrostatic pressure is proposed.This method easily stabilizes the pressure.The effects of different factors such as pressure,type of working fluid,and temperature on the flow characteristics are analyzed.The results show that some flow characteristics of the microfluid are the same as the micro fluid,but some other flow characteristics are different from the micro fluid.These results provide not only new evidence to understand the flow characteristics of microfluid,but also new references to design devices using flow characteristics of microfluid.
