Effects of structural parameters on flow boiling performance of reentrant porous microchannels
TL;DR: In this paper, a series of porous microchannels with Ω-shaped reentrant configurations were developed for application in heat sink cooling, which were fabricated by using a solid-state sintering method under the replication of specially designed Sintering modules.

Flow boiling heat transfer in minichannels at high saturation temperatures: Part II – Assessment of predictive methods and impact of flow regimes
TL;DR: In this article, the reliability of the current flow boiling heat transfer prediction methods for conditions of high saturation temperatures was evaluated with the comparison between experimental results (presented in the first part of this two-part article) and results predicted with the commonly used correlations or models from the literature.

Gas–liquid two-phase flow in microchannels Part I: two-phase flow patterns
TL;DR: In this paper, a systematic experimental investigation of two-phase flow patterns in microchannels was the objective of this study, using air and water, experiments were conducted in circular micro channels with 1.1 and 1.45mm inner diameters, and in semi-triangular (triangular with one corner smoothed) cross-sections with hydraulic diameters 1.09 and 149mm.

A general expression for the correlation of rates of transfer and other phenomena
Stuart W. Churchill,R. Usagi +1 more
TL;DR: The expression Y = (1 + Zn)1/n where Y and Z are expressed in terms of the solutions for asymptotically large and small values of the independent variable is shown to be remarkably successful in correlating rates of transfer for processes which vary uniformly between these limiting cases as discussed by the authors.

The Growth of Vapor Bubbles in Superheated Liquids
M. S. Plesset,S. A. Zwick +1 more
TL;DR: In this article, a solution for the radius of the vapor bubble as a function of time is obtained which is valid for sufficiently large radius, since the radius at which it becomes valid is near the lower limit of experimental observation.
