Experimental Study of Flow Characteristics Through Microtubes

Aloknath K. V., Pradeep M. Kamath

Abstract


In recent years the research in the field of fluid flow at the microscale level has been constantly increasing; due to the rapid growth of technology applications which require the transfer at high heat rates in relatively small spaces and volumes. The present study is conducted to investigate frictional characteristics of circular microchannels using de-ionised water as the fluid medium. The flow-through microchannel is achieved using a peristaltic pump. The diameters of the microchannels used for the experiment are 70 μm, 480 μm and 530 μm. Commercially available stainless steel tubes are used for the analysis. The frictional characteristics of microtubes are obtained at different Reynolds numbers in the laminar region of flow. The results follow the conventional theory of fluid Mechanics (f*Re = 64) except for 70 μm. The experiments revealed that there is no early transition occurred for the flow-through microtubes.
