A General Correlation for Saturated Two-Phase Flow Boiling Heat Transfer Inside Horizontal and Vertical Tubes
TL;DR: In this article, a simple correlation was developed earlier by Kandlikar (1983) for predicting saturated flow boiling heat transfer coefficients inside horizontal and vertical tubes, which was further refined by expanding the data base to 5,246 data points from 24 experimental investigations with ten fluids.

Fundamental issues related to flow boiling in minichannels and microchannels
TL;DR: In this article, the effects of the channel size on the flow patterns and heat transfer and pressure drop performance are reviewed in small hydraulic diameter channels, and the fundamental questions related to the presence of nucleate boiling and characteristics of flow boiling in microchannels and minichannels in comparison to that in the conventional channel sizes (3 mm and above) are addressed.

Surface wettability change during pool boiling of nanofluids and its effect on critical heat flux
TL;DR: In this paper, the authors studied the pool boiling characteristics of dilute dispersions of alumina, zirconia and silica nanoparticles in water and found that a significant enhancement in critical heat flux (CHF) can be achieved at modest nanoparticle concentrations (< 0.1% by volume).

A general correlation for saturated and subcooled flow boiling in tubes and annuli, based on a nucleate pool boiling equation

TL;DR: The authors showed that the eonvective term in the correlation should have a Prandtl number dependence and constructed an accurate predictive method with an explicit nucleate boiling term and without boiling number dependence.
