Transient thermal study of recuperative tube in tube heat exchanger operating in refrigeration system using experimental test and mathematical simulation

A. Saberimoghaddam; M. M Bahri Rasht Abadi

Volume 14, Issue 3 , August 2017, Pages 3-18

  Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling ...  Read More

Improvement of gas separation properties of polyurethane membrane using plasma grafting

P. Azadi; Sh. Hassanajili

Volume 14, Issue 3 , August 2017, Pages 19-30

  In recent years, plasma treatments have given good results since they offer high technological efficiency with low waste generation. One of the most important characteristics of plasma methods is their action only on a thin surface layer, whereas the bulk of sample remains unchanged and the modified ...  Read More

Adsorption and Desorption Process of Chromium Ions Using Magnetic Iron Oxide Nanoparticles and Its Relevant Mechanism

M. Jadidi; N. Etesami; M. Nasr Esfahany

Volume 14, Issue 3 , August 2017, Pages 31-40

  In this study adsorption of Cr(VI) from aqueous solution by Fe3O4 nanoparticles was investigated. Desorption process and recovery of nanoparticles using different solutions were then carried out, and it was observed that NaOH (0.5M) can remove 90% of adsorbed chromium ions. Following the completion of ...  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 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

Methanol crossover and selectivity of nafion/heteropolyacid/montmorillonite nanocomposite proton exchange membranes for DMFC applications

M. Azimi; S.J. Peighambardoust

Volume 14, Issue 3 , August 2017, Pages 65-81

  In this work, we prepared the nafion/montmorillonite/heteropolyacid nanocomposite membranes for direct methanol fuel cells (DMFCs). The analyses such as X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) were conducted to characterize the filler dispersion ...  Read More

Stochastic Comparisons of Probability Distribution Functions with Experimental Data in a Liquid-Liquid Extraction Column for Determination of Drop Size Distributions

Sh. Houshyar; M. Torab-Mostaedi; S. M. A. Moosavian; Seyed Hamed Mousavi; M. Asadollahzadeh

Volume 14, Issue 3 , August 2017, Pages 82-95

  The droplet size distribution in the column is usually represented as the average volume to surface area, known as the Sauter mean drop diameter. It is a key variable in the extraction column design. A study of the drop size distribution and Sauter-mean drop diameter for a liquid-liquid extraction column ...  Read More
