Abstract
The micro-scale flow behavior is significant for the performance of Micro-Electro-Mechanical-Systems (MEMS) devices. With the micro-flow experimental apparatus of pressure range from 0 to 1MPa, the simple liquids with small molecules like non-ion water and several organic liquids (CCL4, C6H5C2H5 and isopropyl alcohol etc.) have been investigated. The flow rates through the microtubes with diameters about 20mum and normalized friction coefficient have been measured. The results show that the flow rate behaviors in microtubes with the diameter mentioned above, for polar or non-polar liquids, are in agreement with the conventional theory of Hagen-Poiseuille flow. It means that N-S equation based on continuous medium still acts well in this case.
