Experimental determination of entropy generation in flat heat pipes

  Heat pipe is a thermodynamic device which transfers heat over considerable distances with a very small temperature drop. Entropy generation can be considered as a significant parameter on heat pipe performance. Major reasons for entropy generation in a heat pipe system are temperature difference between cold and hot reservoirs, frictional losses in the working fluid flows and vapor temperature/pressure drop...

Power draw of the rotor during centrifugal high volume separation of oil and water

  Centrifugal separation of oil and water from streams that is concentrated with oil such as the ones from the oil spill disasters is investigated in this study. The existing theories are largely for Stokes settling of oil drops. In this study, two layers, one rich in oil and another rich in water are allowed to spin in a centrifuge. The tangential velocity profile is derived from the equations of...

Investigation of cutting temperatures distribution in machining heat treated medium carbon steel on a lathe.

  This study was carried out on medium carbon steel subjected to various form of heat treatment operations by assessing the temperature distribution during the machining process. The model of oblique band heat source, moving in the direction of cutting in an infinite medium with an appropriate image heat source was used in this investigation. The model analysis was carried out separately on the chip,...

Productivity improvement of sports goods industrial cluster in Meerut India

  Small scale industries are the main employment provider in any developing country. Most of the micro, small and medium (MSME) scale industries development is due to the efforts of individual entrepreneurs. These entrepreneurs lack the knowledge of various technical and legal aspects of MSMEs. Many times, due to the lack of information, these individual entrepreneurs do not know the latest development in the...
