Three-dimensional laminar flow and heat transfer in a parallel array of microchannels etched on a substrate

Fluid flow and heat transfer in wavy microchannels

“…The local heat transfer coefficient h x is evaluated following the definitions of Shah and London [30], which have been widely employed in similar studies [14,31,32]. For H2 and conjugate simulation: …”

Effect of substrate thickness and material on heat transfer in microchannel heat sinks

“…The author also emphasized on the effect of the wall thickness and material on the heat transfer. Mlcak et al [21] studied laminar flow and heat transfer in a parallel array of rectangular microchannels with a hydraulic diameter of 86.6 mm and found that for the same hydraulic diameter, thermal resistance and friction coefficient values changed insignificantly for aspect ratios larger than 0.5, whereas values of thermal resistances decreased with aspect ratio at lower aspect ratios.…”
