Solar energy is the highly recognized energy source, capable of fulfilling the world’s future energy demands. The solar photovoltaic technology involves the unmediated transformation of sunlight into electricity. A little fraction is converted into electricity and the remaining gets exhausted as unused heat. This results in an increase in the operating temperature of the PV Panel. The conversio...
In the laser deposition of single crystal and directionally-solidified superalloys, it is desired to form laser deposits with high volume fractions of columnar grains by suppressing the columnar-to-equiaxed transition efficiently. In this paper, the influence of beam profile (circular and square shapes) and cooling conditions (natural cooling and forced cooling) on the geometric morphology and ...
Rice drying with infrared radiation has been investigated during recent years and showed promising potential with improved quality and energy efficiency. However, due to limited penetration capability of infrared radiation, thin layer drying may be used in infrared dryer design. The objective of this study was to study the moisture removal characteristics of thin layer rough rice heated by infr...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
The modelling, simulation, fabrication and testing of a microchannel cooling plate are described in this article. The cooling component is to be used in microelectronic packaging applications. The nickelbased micro-channel cooling plate is fabricated on a glass substrate using a two-layer electroforming process borrowed from UV-LIGA. Forced convection of air or liquid is scheduled for this micr...
Forced convective heat transfer plays a significant role in almost all industrial sectors. Examples include cooling of microelectronics, process intensification in the chemical industry, heat exchange/waste heat recovery in power plants and cooling of car engines, to name but a few. In special, a study of forced convective laminar boundary layer behaviour on a flat plate has attracted the atten...
