TL;DR: In this article, a general correlation for heat transfer during subcooled boiling in tubes was compared with a large amount of varied data for boiling in cylindrical annuli, including the inner tube diameter varied from 4.5 to 42.2 mm and the annular gap from 1 to 6.6 mm.
Abstract: A general correlation for heat transfer during subcooled boiling in tubes was compared with a large amount of varied data for boiling in cylindrical annuli. The data include the fluids water, R-113, and methanol; mass fluxes from 2 78 to 7774 kg/m1 s; heat fluxes from 0.03 to 4.4 MW/m2; liquid subcooling from 2 to 109°C; and reduced pressures from 0.009 to 0.89. The inner tube diameter varied from 4.5 to 42.2 mm and the annular gap from 1 to 6.6 mm. The data include heating of the inner, outer, and both tubes of the annuli. The 450 representative data points from all studies are correlated with a mean deviation of 8.9%.

TL;DR: In this paper, the resorption working pair of BaCl2-MnCl2−NH3, which has the similar working requirements for the heat source and cooling source, and also could satisfy the similar refrigeration requirements with the adsorption worked pair of CaCl2, NH3, is studied by simulation and experiments.

TL;DR: In this article, the authors compared the cooling efficiency of oil-in-water emulsion jet with a pure water jet and estimated the transient cooling heat fluxes on the quenched side by coupling the measurement of the temperature field of the other side (rear face) with a semi-analytical inverse heat conduction model.

TL;DR: In this article, heat transfer analysis on a newly proposed cryogenic cooling system is performed for HTS transformers to be operated at 63-66 K. In the proposed system, HTS pancake windings are immersed in a liquid nitrogen bath where the liquid is cooled simply by colder copper sheets vertically extended from the coldhead of a cryocooler.

TL;DR: In this paper, a reduced-order model with sub-cooled boiling was developed, which includes a modal kinetics with the fundamental mode and the first subcritical one, and two channels representing both halves of the reactor core.
