TLDR
In this article, a perforated plate-spray column in which a volatile dispersed phase evaporates while rising in the continuous, counterflowing, immiscible phase is presented.Abstract:
Transfer characteristics are presented for a perforated plate-spray column in which a volatile dispersed phase evaporates while rising in the continuous, counterflowing, immiscible phase. Optimal column heights, volumetric transfer coefficients, holdup, and foam heights are reported as functions of flow rate and temperature approach for a pentane-water system, A comparison with related studies is presented.read more

Heat transfer prediction for a direct contact ice thermal energy storage
TL;DR: In this paper, a cold two-phase refrigerant (R12 or R22) is injected into water kept in a storage tank to exchange heat with the water directly, and the water temperature is reduced to the freezing point, and ice could be formed.

Turbulent direct-contact heat transfer between two immiscible fluids
TL;DR: In this paper, an algebraic one-dimensional thermal model accounting for the axial evolution of the phase temperatures coupled with drop breakup is developed and validated by the experimental thermal results in the DCHE.

Measuring the Average Volumetric Heat Transfer Coefficient of a Liquid-Liquid-Vapour Direct Contact Heat Exchanger
TL;DR: In this paper, the average volumetric heat transfer coefficient in a spray column liquid-liquid-vapour direct contact evaporator has been experimentally investigated using a cylindrical Perspex tube of diameter 10 cm and height and 150 cm.

Equation of motion of an expanding vapour drop in an immiscible liquid medium
Anatol Selecki,Leon Gradoń +1 more
TL;DR: Using the description suggested by Sideman for the internal evaporation of a drop with the growth of a liquid sheath suspended from the lower part of the expanding bubble, an equation describing the motion of such a system is derived as discussed by the authors.
