In the present work, micro-electric discharge machining (micro-EDM) of Ti-6Al-V alloy with tungsten carbide electrode has been performed. Ti-6Al-4V, which is difficult to machine via conventional techniques, however, can be easily machined EDM machining, careful selection parameters for getting optimum results. this study, effect various input parameters; current, voltage, frequency, and width, on output parameter viz., metal removal rate (MRR), tool wear (TWR), overcut (OC) are studied....
This paper describes the effect of various flushing conditions on accuracy deep holes drilled via micro electrical discharge machining (EDM) machining. Copper tubes were used for hole drilling in copper. Various dielectric (side jet flushing, through combined with side immersion flushing) evaluated their diameter variation, overcut and circularity at workpiece entrance exit drilled. Through observed suitable whereas its combination unsuitable higher aspect ratios holes.
The solar air heater (SAH) is a very simple and economical device, but its thermal performance quite poor. Boosting the heat transfer between absorber plates airflow can improve of heater. Applying artificial roughness to plate unique method for improving heaters compared other methods. In this study, diagonally chamfered cuboids were utilized as elements investigate enhancement This achieved by attaching surface. A thorough experimental investigation was carried out examine how affects...
A very common technique to improve the thermo hydraulic performance of solar air heater is providing artificial roughness on absorber plate. Diagonally chamfered cuboids has been used generate and applied surface. numerical study performed enhancement for thoroughness parameters relative pitch (transverse longitudinal) 6 14, cross section from 8 mm 14 height 0.44 0.088. The Reynolds number kept in range 5000 22500 with a constant heat flux 1000 W/m2 computation conducted by using ANSYS...
The idea of introducing artificial roughness on absorber plate to improve the thermal performance a solar air heater is very common now days. technique uses concept providing by imbedded element in heater. Diagonally chamfered cuboids have been used as current study. A numerical study performed investigate enhancement thermo-hydraulic for various affecting parameters such Relative Roughness Pitch (Transverse and Longitudinal) 6 14, cross section from 8 mm 14 relative height 0.44 0.088. range...
A very simple and economical device used for harnessing freely available energy from sun is solar air heater. But these heaters are inefficient due to the low co-efficient of heat air. Making artificially rough absorber plate common amongst various techniques applied on heater enhance performance. Square elements cut diagonally glued surface generate roughness. The impact roughness parameters such Relative height (RRH) 0.44 0.077, pitch(RRP) 3 9 square element arm length (ALSE) 4 mm 10...
