TL;DR: In this article, a composite correlation for pool boiling critical heat flux (CHF) is proposed, accounting for the conduction and hydrodynamic limits, as well as the effects of pressure, subcooling, and length.

TL;DR: In this article, a detailed map of the flow sub-regimes in a shear-driven liquid film flow of water and FC-72 have been obtained for a 2-mm channel operating at room temperature.

TL;DR: In this paper, an experimental investigation into the effects of pressure and subcooling on the pool boiling critical heat flux from a bare silicon chip-like heater and from a silicon heater coated with microporous layers is reported.

TL;DR: In this article, the authors examined the influence of the dynamic solid/liquid contact angle and contact angle hysteresis on the incipience superheat of highly-wetting liquids and found that variations in contact angle induced by changes in the direction and magnitude of the liquid/vapor interface velocity can substantially affect the formation of bubble embryos.

TL;DR: In this article, the authors describe the nano-TIM approaches taken and results obtained by four teams responding to the DARPA challenge of pursuing the development of low thermal resistance of 1 mm2 K/W and high compliance and reliability TIMs.
