A direct contact type ice generator for seawater freezing desalination using LNG cold energy
TL;DR: In this paper, a direct contact type ice generator, which integrates some special designs such as jacketed cylinder, nozzle arrangement and gas floatation, was developed to improve heat transfer and phase separation in the Seawater freezing desalination (SFD) process.

Experimental investigation on fluid flow and heat transfer characteristics of a submerged combustion vaporizer
TL;DR: In this paper, a visual experimental apparatus was established to have a comprehensive knowledge about fluid flow and heat transfer performance of submerged combustion vaporizer (SCV), and two new empirical Nusselt number correlations were regressed to predict the shell-side and tube-side heat transfer characteristics of SCV.

Convective heat transfer measurements in a vapour-liquid-liquid three-phase direct contact heat exchanger
TL;DR: In this paper, the authors investigated the heat transfer associated with the direct contact condensation of pentane vapour bubbles in a three-phase direct-contact condenser, which is used in a cycle with a solar water heater and heat recovery systems.

Direct-contact heat transfer with change of phase: Evaporation of drops in an immiscible liquid medium
Samuel Sideman,Yehuda Taitel +1 more
TL;DR: The transfer characteristics of volatile liquid drops evaporating while rising in a column of immiscible liquid are presented in this paper, where a study of cine-camera films taken during the heat-transfer process rendered information regarding the velocities and evaporation rates of butane and pentane drops.

Evaporation of single liquid drops in an immiscible liquid at elevated pressures: experimental study with n-pentane and R 113 drops in water
Yasushi Shimizu,Yasuhiko H. Mori +1 more
TL;DR: In this article, the authors dealt with direct contact evaporation of single liquid drops in a stagnant medium of an immiscible liquid under moderately elevated pressures. But their experiments were performed with n-pentane and R 113 drops injected into water under pressures of up to 0.48 MPa.
