Prediction of erosion rate in gas-solid flow using computational fluid dynamics (CFD): focus on geometrical parameters

K. Jalalvandi; A. Parvareh

Volume 20, Issue 2 , August 2023, , Pages 33-49

https://doi.org/10.22034/ijche.2023.402980.1495

Abstract
  In this study, the fluid flow together with solid particles has been studied using Computational Fluid Dynamics (CFD). The gas-solid flow (air and sand particles with the size of 150 µm) inside a 76.2 mm diameter pipe with various bend angles including 45, 60, 90, 120, 135, and 180° was modelled ...  Read More

M. Ghanbarnezhad; A. Parvareh; M. Moraveji; S. Jorfi

Volume 20, Issue 1 , March 2023, , Pages 54-66

https://doi.org/10.22034/ijche.2023.394803.1489

Abstract
  The Fe3O4/MW-CNT composite was prepared for a hybrid photo-catalyst-assisted electrochemical process for the removal of BTX contamination from wastewater. Oxidation of multi-walled carbon nanotube was conducted by different treatments including acid treatment and hydrogen peroxide. The XRD, FTIR, SEM, ...  Read More

Optimization of the Adsorption of Pb(II) and Zn(II) onto the EDTA-Modified MnO2/Chitosan/Fe3O4 Nanocomposite from an Aqueous Solution Using RSM According to the CCD Method

Adel Panahadeh; Arsalan Parvareh; Mostafa Moraveji

Volume 18, Issue 3 , September 2021, , Pages 33-51

https://doi.org/10.22034/ijche.2022.314204.1414

Abstract
  The central composite design (CCD) was employed to investigate the adsorption of Pb(II) and Zn(II) metal ions as well as methylene blue (MB) as an aromatic anion by a new EDTA/MnO2/CS/Fe3O4 synthesized nanocomposite. The effect of possible affective factors including the contaminant concentration (20-200 ...  Read More

Biodiesel production from soybean oil using ionic liquid as a catalyst in a microreactor

F. Mohammadi; M. Rahimi; A. Parvareh; M. Feyzi

Volume 15, Issue 1 , February 2018, , Pages 102-114

Abstract
  In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content ...  Read More

investigation of mercaptan removal from Kerosene using passive mixing tools: Experimental study and CFD modeling

A. Parvareh; . Parvizi

Volume 14, Issue 3 , August 2017, , Pages 55-64

Abstract
  Abstract In this work, the role of appropriate mixing for mercaptan removal from Kerosene using caustic soda has been investigated in the pilot scale. Static mixer at different condition has been used as a passive mixing tool to achieve proper mixing and consequently high performance of mercaptan removal. ...  Read More

Experimental and CFD Study of the Tube Configuration Effect on the Shell-Side Thermal Performance in a Shell and Helically Coiled Tube Heat Exchanger

R. Beigzadeh; A. Parvareh; M. Rahimi

Volume 12, Issue 2 , April 2015, , Pages 13-25

Abstract
  "> Despite numerous studies of shell and helically coiled tube heat exchangers, a few investigations on the heat transfer and flow characteristic consider the geometrical effects like coil pitch. Moreover, this scarcity is highlighted for the shell side of this type of heat exchangers. This study ...  Read More
