Evaporation of pure fluids and mixtures in a microchannel tube
… of two-phase flow in microchannel tube. Six pure fluids (R134a, R32, R1234ze(E), R1234yf, R1233zd(E), and R1336mzz(Z)) are tested, and they have significant difference in properties. The experiments are conducted in a 24-port microchannel tube with an averaged hydraulic diameter of 0.643 mm. …

Fluid-phase thermodynamics from molecular-level properties and interactions based in quantum theory
… capability to predict volumetric properties of pure fluids and vapor/liquid equilibrium properties of mixture systems. This work develops a bridge from chemistry at the molecular level to the statistical mechanics at the macroscopic system level. The rigorous properties of functional groups lead …

Fluctuations, Phase Separation and Wetting Films near Liquid-Gas Critical Point
… on Earth limits the study of the properties of pure fluids near critical point because they become stratified under their own weight. Near the critical point, all thermodynamic properties either diverge or converge and the heating and cooling cause instabilities of the convective flow as a …

Vapour-Liquid Equilibria within Nanoporous Media
… research. Included in this report are studies of pure fluids and their mixtures, confined in titania and silica catalyst supports. These investigations are conducted at industrially-relevant, high-temperature (≥ 180 °C) and high-pressure conditions (up to 13 bar), made possible by a pilot-scale …

The Effect Of Colloidal Stability On The Heat Transfer Characteristics Of Nanosilica Dispersed Fluids
Addition of nano particles to cooling fluids has shown marked improvement in the heat transfer capabilities. Nanofluids, liquids that contain dispersed nanoparticles, are an emerging class of fluids that have great potential in many applications. There is a need to understand the fundamental …

PVTX and Raman Spectral Properties of Fluids at Elevated Pressures and Temperatures
Fluids are associated with a wide range of physical and chemical processes in the Earth, including transporting and concentrating important ore elements such as Cu, Au, Zn, and Pb. Significant amounts of fluid may be generated as a result of dehydration or decarbonation reactions, and the volatile …
