Investigation. effect. of mixed. matrix. membranes’. structural. parameters. on their. effective. gaseous. penetrant. diffusion. ratio using. CFD tools

Mona Morovat; Omid Bakhtiari

Volume 19, Issue 4 , December 2022


  Ability and compatibility of the membrane processes for gas separation are evaluated by their membranes’ permeability and selectivity where both have been tried to enhance in promising membrane generation of mixed matrix membranes (MMMs). In the current study, two- and three-dimensional models ...  Read More

CFD Modeling of the Dehydration of Biofuels with the 2D MXene Membrane using the Pervaporation Process

N. Hajilary; S. Hashemi; M. Hajiabadi

Volume 19, Issue 1 , March 2022, , Pages 77-89


  MXene membranes perform well in biofuel separation due to their excellent hydrophilicity, flexibility, and mechanical strength. For the first time, computational fluid dynamics was used to model the dehydration of ethanol through the pervaporation system by the MXene membrane. We discretized the momentum ...  Read More

Effects of Vertical Temperature Gradient on Heavy Gas Dispersion in Build up Area
Volume 6, Issue 3 , July 2009, , Pages 26-45

  ewline"> Dispersion of heavy gases is considered to be more hazardous than the passive ones because it takes place more slowly. When the gas is accidentally released at ground level or where there are many obstacles in the area it is considered to be a heavy gas. In this paper, based on the extensive ...  Read More

A Study on Liquid-liquid Mixing in a Stirred Tank with a 6-Blade Rushton Turbine
Volume 5, Issue 4 , October 2008, , Pages 12-22

  The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The ...  Read More
