An investigation into the effect of regular polygonal cross-sections on thethermal performance of microchannel heat sinks

Zanco Journal of Pure and Applied Sciences, 2019
Microchannel heat sinks can be constructed from the channels with various geometries in cross-section. Their shape and size may have considerable effects on the hydraulic and thermal performance of a heat sink.

Modeling considerations about a microchannel heat sink

Physics of Fluids
Many computational studies on hotspot microfluidic cooling devices found in the literature rely on simplified assumptions and conventions that do not capture the full complexity of the conjugate thermal problem, such as constant thermophysical fluid properties, radiation, and free air convection on the external walls.

Modelling pressure fluctuations during flow boiling in microchannels with inlet compressibility and resistance [PDF]

, 2009
Confined bubble growth during flow boiling at low pressures in microchannels generates pressure fluctuations that may cause transient flow reversals that disturb the flow distribution in heat sinks formed of parallel channels joined by plena.
