[1]Bhabha Atomic Research Centre, Mumbai, India

Shielded transportation casks are commonly used for transportation and storage of radioactive waste materials. Design approval of such casks by regulatory authority is subject to its compliance with a thermal test (among other tests) Due to exposure of cask to fire , there is a ... En savoir plus

Modeling Phase Separation of Toluene-water in a Horizontal Settler

E. Barega, E. Zondervan, and A.B. De Haan
Eindhoven University of Technology, Dep. Chemistry and Chemical Engineering, Eindhoven, the Netherlands

The mixer-settler principle is commonly used for industrial extraction processes. This is done by mixing the two immiscible liquids to perform mass transfer and subsequently separating them in gravity settler. However, when drop size becomes small, separation in a settler becomes ... En savoir plus

Design and Simulation of 3D ZnO Nanowire Based Gas Sensors for Conductivity Studies

N. Gouthami, D. Parthiban, M. Alagappan, and G. Anju
PSG College of Technology
Coimbatore
Tamil Nadu, India

The objective of this paper is to design a 3D Gas Sensor for sensing Hydrogen gas and to increase the conductivity at nano level. In this novel design, nanorods act as the sensing layer. The sensitivity towards gas adsorption is found to be increased due to its high surface to volume ... En savoir plus

Department of Electric and Electronic Engineering
University of Cagliari
Cagliari, Italy

In this work an innovative wind power generation in urban areas is proposed. The generation system substitutes the roof of the building and it consists of a static part, the stator, and a moving part, called impeller, which is a centripetal turbine with vertical axis of rotation. Since ... En savoir plus

Equation Based Heat and Mass Transfer in Porous Media

S. Pemberton[1], K. Ekici[1], R. Arimilli[1]
[1]The University of Tennessee, Knoxville, TN, USA

Perspiration during intense physical activity is an essential part of human thermoregulation. Clothing affects the cooling rate of the body. Heat and water vapor are coupled through evaporation and transported through the fabric. A model of the above system was developed for fabrics of ... En savoir plus
