Effect of Minimum Quantity Lubrication on temperature dissipation in machining of AISI 4130
Abstract: Abstract: Minimum Quantity Lubrication (MQL) has good cooling effects and is gaining importance due to environment friendly machining. MQL proving to be an alternative to flood cooling besides it reduces the cost. The present study is based on MQL parameters performance on temperature of grinding zone. Experiment results were compared of three different vegetable oils. It was found out if with controlled grinding environment MQL can be at par with …

Effective efficiency of return flow solar air heater
Abstract: In this paper, the effective efficiency of a return flow solar collector with artificial roughness in the form of V shaped ribs is presented as a function of parameters pertaining to roughness like angle of attack (α), and relative roughness height (e/D) and other relevant operating parameters. Analytical methods were used & governing energy balance equations are used to evaluate results. Plots on these aspects have been presented and discussed …

Vortex Tube Refrigeration System under Different Working Parameters: A Study
Abstract: AbstractThe vortex tube is a small, likable, and marvelous mechanical device used as refrigeration machine. Vortex tube is a device having no moving parts that separates the high pressure stream flow into two streams namely hot and cold at defined pressure. At the separation of two streams, one stream rejects the heat and becomes colder while the other receives the rejected heat and becomes hotter as compared to previous one. …
