碩士 === 淡江大學 === 機械與機電工程學系 === 91 === Air flow through microtubes with diameters ranging from 0.287 to 0.647 mm was investigated experimentally. By the precisely image-processing analysis, all our glass microtubes had the roundness deviation less than 6%. Using the Alpha-step profiler, the average surface roughness of the microtube inner wall was found below 15nm.Pressure drop and flow rates were measured to analyze the flow characteristics.
The experimental results indicate that friction factor f obtained from Fanno-line flow function agree well with Poiseuille (f = 64/Re) and Blasius (f = 0.316/Re0.25) equations in laminar and turbulent flow.
