Effects of Specific Heat Ratio and Cut-off Ratio on the Performance of an Irreversible Dual Cycle
Abstract: This study is aimed to investigate the effects of specific heat ratio and cut-off ratio on the Dual cycle performance. The variation in the power output and thermal efficiency with compression ratio, peak temperature of the cycle, specific heat ratio and cut-off ratio are presented. The result shows that with decrease in compression ratio up to a value, the increase in specific ratio lowers specific work output and increases efficiency …

Optimization of Performance Parameters for Material Removal Rate in Side Flushing Form of Die Sink EDM
Abstract: In the present scenario, electrical discharge machining (EDM) is a well-established machining option for manufacturing geometrically complex or hard material parts that are extremely difficult to machine by conventional machining processes. EDM researchers have explored a number of ways to improve the efficiency including some unique experimental concepts. The operating performance measures of side flushing type of electrical discharge machining process on EN-31 die steel using copper electrode are being …
