TL;DR: In this article, an absorption-compression hybrid refrigeration cycle has been studied on the basis of available data of working pair 1, 1,1,2-tetrafluoroethane (R134a) and dimethylformamide (DMF).

TL;DR: In this paper, the effects of surface wettability on two-phase pressure drop of flow boiling of water at atmospheric pressure were investigated in a single rectangular channel with static contact angles of 26°, 49°, 63° and 103°.

TL;DR: In this article, the motion of a vapor bubble in sub-cooled boiling was studied experimentally using slightly subcooled water, ethanol, and carbon-tetrachloride under the atmospheric pressure, and the experimental data for the collapse stage were well correlated by the equations which were derived by assuming a laminar heat trasfrer between the spherical bubble and the surrounding liquid with uniform subcoolings.
Abstract: The motion of a vapor bubble in subcooled boiling was studied experimentally using slightly subcooled water, ethanol, and carbon-tetrachloride under the atmospheric pressure. The degree of subcooling ranged usually from about 2°C to 50°C, and in a few extreme cases it was extended to below 1°C. The experimental data for the collapse stage were found to be well correlated by the equations which were derived by assuming a laminar heat trasfrer between the spherical bubble and the surrounding liquid with uniform subcoolings.

TL;DR: In this paper, the distribution and growth of water droplets are monitored across the surface at different relative humidities (45, 50, 55, and 70%) at a constant surface subcooling temperature of 15°C below the ambient temperature (20°C), and the overall volumetric rate of condensation on the surface is also assessed as a function of time and ambient relative humidity.

TL;DR: In this paper, the authors present experimental results of observation of liquid-solid contact and bubble behaviors around the critical heat flux of saturated and subcooled pool boiling on a plate of single crystal sapphire.
