Modeling Of Liquid Flow In A Packed Bed Under Influence Of Gas Flow
(2009-03-05)
The aim of the current study is to model (non-wetting) liquid flow in a packed bed under the influence of gas flow. It has been observed experimentally that non-wetting liquid flows in a packed bed in form of small droplets ...
Development And Validation Of Two-Dimensional Mathematical Model Of Boron Carbide Manufacturing Process
(2009-03-06)
Boron carbide is produced in a heat resistance furnace using boric oxide and petroleum coke as the raw materials. In this process, a large current is passed through the graphite rod located at the center of the cylindrical ...

(2009-03-05)
Dilute Mg alloys are exclusively identified for wrought structural applications in automotive industry. Any improvement in mechanical properties of alloys is possible only by grain size refinement and by the development ...
Structure, Microstructure and Magnetic Properties of Fe-Ga and R-Fe based Magnetostrictive Thin Films
(2018-02-27)
Magnetostrictive materials belong to an important class of smart magnetic materials which have potential applications as ultrasonic transducers, sensors, actuators, delay lines, energy harvesting devices etc. Although, ...
Evolution of Microstructure and Texture during Severe Plastic Deformation of a Magnesium-Cerium Alloy
(2018-01-03)
Magnesium alloys have poor formability at room temperature, due to a limited number of slip systems owing to the hexagonal closed packed structure of magnesium. One possibility to increase the formability of magnesium ...
First-Principles Studies of Point Defects and Phase Transformations in Materials
(2018-01-18)
The functional and mechanical properties of a material are often determined by the defects in them. A thorough understanding of the relationship between the defects and the properties allows for tailoring a material’s ...
Microstructural, Mechanical and Oxidation Behavior of Ni-Al-Zr Intermetallic Eutectic Alloys
(2018-01-04)
The excellent high temperature microstructure stability, high strength, and oxidation resistance of intermetallics has for long driven the development of intermetallic based alloys. More recent studies demonstrated attractive ...
Some Processing and Mechanical Behavior Related Issues in Ti-Ni Based Shape Memory Alloys
(2017-11-30)
Shape memory alloys (SMAs) exhibit unique combination of structural and functional properties and hence have a variety of current and potential applications. The mechanical behaviour of SMAs, in particular the influence ...
Effect of Li Addition on the Plasticity of AZ31 Mg-Alloy
(2017-11-14)
Mg-alloys, despite being the lightest structural metallic materials, find limited applications due to their poor workability, which is due to the hcp structure that does not provide sufficient number of independent slip ...
