TL;DR: In this article, a modified mechanistic force-balance model for bubble departure in subcooled flow boiling has been proposed to evaluate the predictive accuracy of the predicted bubble departure diameter in a wide range of orientation angle, subcooling, heat flux, mass flux and pressure conditions.

TL;DR: In this paper, the effect of pore size and pore thickness on the critical heat flux (CHF) in boiling heat transfer was investigated using carefully engineered surfaces, and it was shown that, for a fixed pore diameter (∼20 nm), there is an optimum layer thickness for which the CHF value is maximum, corresponding to ∼115% enhancement over the value for uncoated surfaces.

TL;DR: In this paper, the authors used a combination of high-speed video, infrared thermography, and particle image velocimetry to investigate nucleation, growth, and detachment of steam bubbles during nucleate boiling of a water pool at atmospheric pressure.

TL;DR: In this article, the spectral dependence of optical properties in the optical materials has been taken into account to improve the accuracy of infrared thermometry in boiling heat transfer investigations, which is suitable for heaters consisting of a thin infrared (IR) opaque conductive film coated on one side of a flat and IR semi-transparent substrate.

TL;DR: In this article, the authors used high-speed infrared (IR) thermometry through an IR-transparent silicon wafer heater to detect the liquid-vapor-solid triple contact line.
