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 …
