As a clean and energy-saving natural gas purification separation device, the supersonic separator's internal gas-liquid mechanism needs to be explored. However, complex three-field (gas, droplet, liquid film) two-phase liquid) condensation flow challenges numerical modeling. Most studies are limited tracking phase droplets ignore effects of film change on water vapor removal. In present study, ...

Supersonic separator is a kind of natural gas dehydration device with great potential, but its internal mass and heat transfer process has not been fully studied. In this study, novel three-field two-fluid model described by Eulerian-Eulerian approach for supersonic considering the between gas, liquid droplets, film was developed validated. The interphase slip, latent heat, flux, phase change r...

In this study, a mathematical model for the supersonic condensate flow of natural gas to understand its condensation process in separator has been proposed. The effects export back pressure, inlet temperature, and pressure on parameters were investigated. results indicate that position moves forward with increase decrease temperature. A method determining optimal range operating (export pressur...

Proper estimation of droplet growth rate plays a crucial role on appropriate prediction of supersonic separators performance for separation of fine droplets from a gas stream. Up to now, all available researches employ empirical or semi-empirical correlations to define the relationship between droplet growth rate (dr/dt) and other operating variables such as temperatures (T and TL), Pressure (P...

Optimizing the desired properties for stretch monolayer separators used in Lithium-ion batteries has been a challenge. In the present study a cellulose nanofiber/PET nonwoven composite separator is successfully fabricated, using a wet-laid nonwoven (papermaking) process, which can attain optimal properties in wettability, mechanical strength, thermal resistance, and electrochemical performance ...

the performance of the electric submersible pump (esp) significantly affected by gas void fraction (gvf). thus, using of a rotary gas separator (rgs) is a suitable solution for this issue. the performance of the rgs is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and gvf. in this study, the influences of gvf, viscosity, and ...

In this research, inorganic material type and content influence on coating of commercially available polypropylene (PP) separator were studied for improving its performance and safety as lithium ion battery separator. Heat-resistant nanopowders of Al2O3, SiO2 and ZrO2 were coated using polyvinylidene fluoride (PVDF) binder. Coating effects on the separators morphology, wettability, high tempera...
