Heat transfer for water flow in trapezoidal silicon microchannels
TL;DR: In this article, the authors investigated heat transfer characteristics of water flowing through trapezoidal silicon microchannels with a hydraulic diameter ranging from 62 to 169 μm and found that the measured lower Nusselt numbers may be due to the effects of surface roughness of the microchannel walls.

An Analytical Study of the Effects of Surface Roughness on Boundary-Layer Transition
TL;DR: In this article, the effects of surface roughness on the transition of a laminar boundary layer are investigated, which can distort the mean velocity and temperature profiles thus altering the stability characteristics of the layer and induce additional disturbances to the boundary layer which may lead to an earlier transition.
