The storage of hydrogen as an absorbed element in metal hydride bottles is a promising technique for energy storage. In this work, a three-dimensional model of a charging process in a metal hydride container has been developed to simulate the absorption reaction and resultant heat and mass transport phenomena in metal hydride vessels. The model has been experimentally validated showing a good ...

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 to see the feasibility of direct heating technique for heat treatment application. At present, heat treatment ...

Transformations in polymers, such as polymerisation, melting/crystallization, and phase separation/remixing, are associated with changes in both rheological and thermal properties. To permit simultaneous calorimetric and rheometric measurements, the RheoDSC was developed. The RheoDSC combines two commercial instruments, a TA Instruments Q2000 DSC and a TA Instruments AR-G2 dynamic rheometer. A ...

Many industrial, especially heterogeneously catalysed, processes are characterised by a strong interaction between the reaction kinetics and transport phenomena. Because experiments in laboratory scale can be very time- and cost-intensive, Temkin andKul’kova developed a new reactor design for the direct testing of industrial catalysts. Based on this concept of linearly alternating catalyst and ...

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from strict site-related conditions, mainly related to the reservoir rock’s permeability. In this work, SP ...

An analysis to quantify the flow inside the narrow channels of an ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) adsorbent bed is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Heaters and associated fins inside the adsorbent beds form many small parallel channels which are rectangular in cross section. The channels are ...

The optimized design of a waveguide applicator has been proposed for superficial microwave hyperthermia using COMSOL Multiphysics 3.5a. In microwave hyperthermia cancer treatment body tissue is exposed to high temperatures using external and internal heating devices. Non-Invasive or external hyperthermia is used to treat tumors that are in or just below the skin (superficial). Non-invasive ...
