Two-dimensional Fluid Simulation of an RF Capacitively Coupled Ar/H2 Discharge

L. Tong[1]
[1]Keisoku Engineering System Co., Ltd., Tokyo, Japan

Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... Read More

Modelling and Simulation of Simultaneous Intrinsic Kinetics, Hydrogen Transport and Heat Transfer in Complex Hydride Hydrogen Storage Systems

G. A. Lozano, J. M. Bellosta von Colbe, T. Klassen, and M. Dornheim
Institute of Materials Research
Materials Technology
Helmholzt-Zentrum Geesthacht
Geesthacht, Germany

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Read More

Simulation and Experimental Validation of Direct Heating of Dhruva Fuel Rod for β Heat Treatment

B. Patidar, A. P. Tiwari[1], V. Patidar[1], M. M. Hussain[1], K. K. Abdulla[1]
[1]Bhabha Atomic Research Centre, Mumbai, Maharashatra, India

β heat treatment of Uranium rods is carried out for randomization of oriented grains (called texture) developed during hot rolling or hot extrusion operation. During this process, Uranium rods undergo heating of up to 740 Deg C followed by water quenching. The objective of this work is ... Read More
