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

Inventions, 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 ...

Distribution and Mass Transfer of Gas–Liquid Two-Phase Flow in Comb-Shaped Microchannels

, 2023
For gas–liquid two-phase flow in comb-shaped microchannels, operating conditions could change the flow pattern and the uniformity of flow distribution and further affect the mass transfer performance. In this study, the hydrodynamics and mass transfer of

Numerical Investigation on a Liquid–Gas Ejector for Carbon Dioxide Removal Using Amine Solution: Hydrodynamics and Mass Transfer Evaluation

Applied Sciences, 2022
The present study investigates the hydrodynamics and mass transfer of the liquid–gas ejector using three-dimensional (air–water) and two-dimensional (CO2/air-MEA (Monoethanolamine) solution) computational fluid dynamics (CFD) modeling. For 3D simulation,

Rarefied gas effects on the aerodynamics of high area-to-mass ratio spacecraft in orbit [PDF]

, 2013
The aerodynamic situation of a satellite-on-a-chip operating in low Earth orbit bears some resemblance to a classical Crookes radiometer. The large area-to-mass ratio characteristic of a SpaceChip means that very small surface-dependent forces produce ...

CFD simulations of the mass transfer behavior of tar simulant on silicon oil in an absorber

Case Studies in Thermal Engineering, 2022
Oil washing for tar removal had achieved considerable success. However, hardly any research focused on the exploration of mass transfer in the tar absorber, especially due to viscosity.

Membrane Gas Absorbers for H2S Removal - Design, Operation and Technology Integration into Existing Odour Treatment Strategies. [PDF]

, 2005
A hollow fibre (HF) polypropylene membrane gas absorber was investigated for the removal of hydrogen sulphide (H2S) from gas streams. Gas concentrations between 25-2010 ppmV were fed into the shell side of a membrane module whilst water-NaOH solutions
