摘要

With the development of Micro-Electro-Mechanical-Systems(MEMS), the microscale flow characteristics had attracted the great interests of scientific researchers. The key question is whether the macro flow rules are still valid or the micro flow has its own special flow characteristics which can be altered from the macro flow rules or it is a whole new theory. All these questions must be experimented to gain the final result. In this paper, the behavior of liquid was studied in microchannels with diameters ranging from 13μm to 100μm. By using different microtube diameter and length to explore the flow characteristics of microfluids. The results are basically in accordance with macroscale conventional theory; the N-S equation still acts well.
