Saturation nucleate pool boiling - a simple correlation
TL;DR: In this paper, the authors fitted experimental data for saturation nucleate pool boiling with a correlation of new simple type, using only reduced pressure, molecular weight and surface roughness, which made it easier to see the wood among the trees, and see where data are lacking or contradictory.
Journal ArticleDOI
Heat pipes in modern heat exchangers
TL;DR: In this paper, a review of heat pipe developments in the former Soviet Union countries is presented, and some new results obtained in USA and Europe are also included in the review. But none of the results are available for the former USSR.

Advances and Unsolved Issues in Pulsating Heat Pipes
Yuwen Zhang,Amir Faghri +1 more
TL;DR: Pulsating (or oscillating) heat pipes (PHP or OHP) are new two-phase heat transfer devices that rely on the oscillatory flow of liquid slug and vapor plug in a long miniature tube bent into many turns.

Journal of Heat Transfer Policy on Reporting Uncertainties in Experimental Measurements and Results
TL;DR: The Journnal of Heat Transfer (JHT) as discussed by the authors has recognized the need to prepare a set of guidelines on estimating experimental uncertainty, which were used to ensure uniformity of presenting experimental data and to raise the authors' awareness regarding the importance of giving a more precise statement about their measurement uncertainties.
