Periodic boiling in parallel micro-channels at low vapor quality
TL;DR: In this paper, the authors evaluated instability and heat transfer phenomenon under condition of periodic flow boiling of water and ethanol in parallel triangular micro-channels, and the dimensionless experimental values of the heat transfer coefficient were presented as the Nusselt number dependence on the Eotvos number and the boiling number.

Two-phase flow instability for boiling in a microchannel heat sink
K.H. Chang,Chin Pan +1 more
TL;DR: In this article, the authors explored experimentally the two-phase flow instability in a microchannel heat sink with 15 parallel microchannels and found that the magnitude of pressure drop oscillations may be used as an index for the appearance of reversed flow.

Numerical simulation of gas–liquid two-phase flow and convective heat transfer in a micro tube
TL;DR: In this article, a finite difference method is used to solve the governing equations, while the level set method is adopted for capturing the interface of gas and liquid, and the simulation is repeated under different conditions of pressure gradient and void fraction.

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.
