An experimental study on flow boiling in microchannels under heating pulses and a methodology for predicting the wall temperature fluctuations
TL;DR: In this paper, the authors provided a fundamental understanding of how the temperature fluctuations caused by transient heat flux are affected by the mass velocity, local vapor quality, average heat flux and the heating pulses waveform, amplitude and its frequency.

Evaporating bubble in a heated capillary: effect of passage on the temperature field of the external wall
TL;DR: In this article, the nonisothermal Taylor liquid-slug-vapor-bubble problem, occurring inside a capillary of circular cross-section, is investigated numerically, and it is shown that wall thickness effects on capillary wall temperature are negligible in terms of diffusion and lag.

Modeling of pressure drop and heat transfer for flow boiling in a mini/micro-channel of rectangular cross-section
TL;DR: In this paper, a 1-dimensional model is proposed to estimate the pressure drop and heat transfer coefficient for flow boiling in a rectangular microchannel, taking into account the pressure fluctuations caused due to the confined bubble growth and the effect of pressure fluctuations on the heat transfer characteristics.

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.
