Surface Roughness Impact on Microchannel Heat Transfer by mohamed.3bdelrashied is a document available to read on EtoBox.
This paper investigates the impact of surface roughness on flow behavior and heat transfer in circular microchannels through experimental methods. Results indicate that increased surface roughness leads to higher friction factors and Nusselt numbers, with a critical Reynolds number for transition from laminar to turbulent flow at approximately 1500. The study concludes that roughness significantly affects microchannel performance, contrasting with traditional macrochannel theories.
