First and Second-Laws Analysis of an Air-Standard Dual Cycle With Heat Loss Consideration

In this article, the first and second-laws analysis of the thermodynamic Dual cycle with considering of heat loss are investigated by using finite-time thermodynamics (FTT). The influences of various factors (e.g. initial temperature of working fluid, constants related to combustion and heat transfer through the cylinder wall) on the performance of Dual cycle are analyzed. As well as, the curve of the first-law efficiency versus compression ratio, the net work output versus compression ratio, the second- law efficiency versus compression ratio and the second-law efficiency versus the first-law efficiency are indicated. The finding results in this article can be useful for analysis of Dual cycles.
