1. Study on the Effect of Humidity on Electrical Properties of Copper-Silica Aerogel

N. Yasrebi; J. Moghaddas

Volume 12, Issue 2 , Spring 2015, Pages 3-12

Abstract
  > Copper-silica aerogel was synthesized by the sol-gel method and was heated at 400, 500 and 600°C for 3 h in the air. The gained materials were named as sample (a), (b) and (c) respectively. Then all samples were characterized by FE-SEM, EDX and FTIR spectroscopy. For resistance measurements ...  Read More

2. 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 , Spring 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
