Flow boiling of water in a circular staggered micro-pin fin heat sink (2008, unknown): “It has been recently shown that the Nusselt number in configuration similar to the present one has different Reynolds number functionality for Re 100 [ 12 ].”
Computational analysis of nanofluid effects on convective heat transfer enhancement of micro-pin-fin heat sinks (2012, background): “The nanofluid flow is assumed incompressible and the inlet Reynolds number is less than 100, hence flow is assumed to be laminar [2].”
Interlayer cooling potential in vertically integrated packages (2008, background): “Low-aspect-ratio pin-fin heat-transfer structures at Reynolds (Re) numbers B1,000 were analyzed by other groups, but only for single-side heat flux with a glass cover on the cavity (Peles et al. 2005; Prasher et al. 2007; Kosar et al. 2007), a configuration that does not reflect the double-side he”
Analysis and active control of pressure-drop flow instabilities in boiling microchannel systems (2010, background): “This length/diameter ratio of 150 is easily attained in microchannels, and this is one reason why so many researchers have observed boiling flow oscillations [6,7,14–22].”
