in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...

The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element. We compile recent studies of the quantum Otto cycle with a harmonic oscillator as a working medium. This model has the advantage that it is analytically trackable. In addition, an experimental realization has been achieved, employing a...

In this study, energetic performance analysis of an endoreversible modified dual cycle is performed. context, the net work and thermal efficiency cycle, are formulated with respect to certain basic design parameters. Also, conditions for maximum investigated, classical cycles, compression ratio that maximizes analytically obtained extreme temperature ratio, isothermal expansion cutoff ratio. Th...

Power output (P), thermal efficiency (η) and ecological function (E) characteristics of an endoreversible Dual-Miller cycle (DMC) with finite speed of the piston and finite rate of heat transfer are investigated by applying finite time thermodynamic (FTT) theory. The parameter expressions of the non-dimensional power output (P), η and non-dimensional ecological function (E) are derived. The rel...
