Flow boiling heat transfer in two-phase micro-channel heat sinks––I. Experimental investigation and assessment of correlation methods (2003, background): “Two-phase hydrodynamic instabilities encountered during flow boiling in microchannel heat sinks, and means of preventing those instabilities have been addressed in a previous study by the authors [ 23 ].”
Two-Phase Microchannel Heat Sinks: Theory, Applications, and Limitations (2011, unknown): “Because it can occur at much lower flow velocities in a two-phase mixture than in pure liquid or vapor flows [13] [14] [15] [16] [17], choking can be a serious limitation to cooling performance when using very small diameters.”
Effects of heat flux, mass flux, vapor quality, and saturation temperature on flow boiling heat transfer in microchannels (2009, background): “…many studies (Chang and Pan, 2007, Chen and Garimella, 2006, Harirchian and Garimella, 2008, Lee and Garimella, 2007, Liu, Lee, and Garimella, 2005, Qu and Mudawar, 2004, Steinke and Kandlikar, 2004, and Wu and Cheng, 2003) have addressed this topic, flow boiling in microchannels has not yet been…”
Universal approach to predicting two-phase frictional pressure drop for adiabatic and condensing mini/micro-channel flows (2012, background): “What distinguishes mini/micro-channels from macro-channels is the significance of surface tension and viscosity effects and negligible body force effects for the former as discussed by Qu and Mudawar [16] and Kim and Mudawar [79].”
Microchannel size effects on local flow boiling heat transfer to a dielectric fluid (2008, methodology): “This is attributed to the rapid increase of vapor quality and early establishment of annular flow in microchannels of very small diameter [6,7,16].”
Refrigerant flow boiling heat transfer in parallel microchannels as a function of local vapor quality (2008, background): “Flow boiling of water in single and parallel microchannels has been investigated by several authors [6, 7, 8, 9,10,11].”
Universal approach to predicting two-phase frictional pressure drop for mini/micro-channel saturated flow boiling (2013, background): “transition to annular flow, and liquid shattered from upstream forms small droplets that are entrained in the vapor core [16].”
History, Advances, and Challenges in Liquid Flow and Flow Boiling Heat Transfer in Microchannels: A Critical Review (2012, background): “Flow boiling instabilities were observed by a number of investigators [120,121,124,129, 133,134,160,161].”
Flow boiling heat transfer in two-phase micro-channel heat sinks--II. Annular two-phase flow model (2003, background): “Flow visualization studies have been performed on water flow boiling in the present micro-channel heat sink, and results were reported in a separate paper by the authors [2].”
Enhancement of pool-boiling heat transfer using nanostructured surfaces on aluminum and copper (2010, background): “In order to accommodate heat flux levels of 1000-10,000 W/cm(2), such as those discussed by Qu and Mudawar [1,3], two phase-flow cooling systems will be required and must be designed in various configurations.”
Review and Comparative Analysis of Studies on Saturated Flow Boiling in Small Channels (2008, background): “1-50 Experiments on convective flow boiling in parallel channels: ♦ Different flow patterns are observed simultaneousl y in various microchannels ♦ Flow instabilities are observed ♦ Surface temperature is almost constant over the en tire surface during boiling Qu and Mudawar (2004) [61] water in cop”
