Abstract

The aim of the study is to determine the effect of a randomly generated rough surface on the laminar flow of a fluid in a microchannel. Two-dimensional axially symmetric microchannels with a circular cross-section in the range of Reynolds number Re = 100-1700 were considered. Flow numerical simulations were performed using the Ansys / Fluent software.
