Investigation on close-coupled gas atomization for Fe-based amorphous powder production via simulation and industrial trials: Part I. Melt breakup behaviors during primary atomization

open access: yesJournal of Materials Research and Technology, 2023
The primary atomization process is simulated by Volume of Fluid (VOF) model and dynamic adaptive mesh method. The influence of melt mass flow rate and atomization pressure on the breakup process is investigated, and the effect of hot gas atomization is ...

Numerical investigation of side arm gas volume fraction in two phase T-junction

open access: yesJournal of Mechanical Engineering and Sciences, 2016
T-junction is commonly installed at the offshore production header as a separator to tap produced gas for downstream process operation. A major issue in the T-junction is the liquid carryover, where excessive liquid flows into the downstream process ...

Absorber design in sour natural gas treatment plants: Impact of process variables on operation and economics = Absorberentwurf für Anlagen zur Behandlung von sauren Erdgasen: Einfluss Prozessparameter auf Betriebsführung und Prozesswirtschaftlichkeit [PDF]

open access: yes, 1985
Two models of absorber have been developed which describe the absorption of H2S and CO2 from natural gases by aqueous di-isopropanolamine (DIPA) or methyl-di-ethanolamine (MDEA) solutions. In these models mass transfer, reaction and equilibrium processes

Mathematical Model of the Working Processes of the Gas Cap of a Piston Pump Installed in the Discharge Line

open access: yesInventions, 2023
A mathematical model of the working processes occurring in the gas cap has been developed on the basic fundamental laws of conservation of energy, mass and motion, and the equation of state, both taking into account the change in the mass of the gas due ...
