Vapor–Liquid Phase separation of He II
Cryogenics, 1998A theory is proposed which uses both the permeability and bubble point diameter of the porous plug to characterize the full range operation of the Vapor Liquid Phase Separation (VLPS) of liquid helium. A computer model has been written based on the theory presented in this paper, which gives good correlation with VLPS data in the literature.

Microphase separation versus the vapor-liquid transition in systems of spherical particles
Journal of Chemical Physics, 1999The conditions, i.e., the interparticle potentials, for which vapor–liquid coexistence is supplanted by microphase separation are examined. The liquid phase is found for potentials with a steeply repulsive core and an attraction of not-too-short a range. To this potential we add a repulsion of longer range than the attraction and find that it breaks up

Vapor-Liquid Separation at Supersonic Velocities
Journal of Engineering for Industry, 1968When a gas mixture at high pressure is expanded to a lower pressure, autorefrigeration often causes some of the heavier components to liquefy. This paper presents a new method for separating components of a gas stream by incorporating isentropic expansion and subsequent inertial separation of the dispersed liquid phase formed.

Prediction and verification of the thermodynamic performance of vapor–liquid separation condenser
Energy, 2013Abstract This paper proposed a computation program to predict the in-tube thermodynamic performance of the LSC (liquid–vapor separation condenser). The refrigerant circuit of the LSC was then optimized using the Penalty Factor with the predicted results.

Thermochimica Acta, 2003
Abstract A novel methodology for the screening of vapor–liquid enrichment in binary homogeneous systems is presented. The methodology is based on the estimation of a separability coefficient from experimental data obtained by thermogravimetry with Fourier transform infrared spectrometry (TG-FTIR) of the evolved gases.

Vacuum separation of zinc-silver alloy: Measurement and modeling of vapor-liquid equilibrium
Vacuum, 2021Abstract Vacuum distillation of a zinc-silver (Zn–Ag) alloy under a system pressure of 5–10 Pa was conducted in the temperature range of 1173–1373 K. The Zn content in the Zn–Ag alloy was reduced from 70.80 wt% to 0.0026 wt% via a single-stage distillation process at a temperature >1373 K.

Vapor–liquid separation of mixtures R134a/R600a at horizontal branch T-junctions
International Journal of Refrigeration, 2020Abstract As a promising separator, T-junction can be easily incorporated into the thermodynamic systems. Previous researches have investigated the phase separation of air-water and pure refrigerants but here the separation performance of mixtures at horizontal branch T-junctions is reported.

A study of carry‐under phenomena in vapor liquid separation
AIChE Journal, 1963Vapor-liquid separation by gravity becomes more difficult when the system volumetric capacity decreases and power density increases. An analytical and experimental study of the carry-under problem (vapor entrained in the downcomer) was conducted on the effects of parameters on the amount of carry- under.

Development Tests of a Vapor/Liquid Separated Two-Phase Fluid Loop
SAE Technical Paper Series, 1997<div class="htmlview paragraph">Two types of evaporators, specially developed for pumped two-phase fluid loop use, are illustratively described with drawings from which inner structures can clearly be seen. A significant difference between the two is such that evaporator exit vapors are usually wet in the first while always dry in the second.
