The Quantum Harmonic Otto Cycle

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...

Occurrence of discontinuities in the performance of finite-time quantum Otto cycles.

We study a quantum Otto cycle in which the strokes are performed in finite time. The cycle involves energy measurements at the end of each stroke to allow for the respective determination of work. We then optimize for the work and efficiency of the cycle by varying the time spent in the different strokes and find that the optimal value of the ratio of time spent on each stroke goes through sudd...

Finite-Time Thermodynamic Modeling and a Comparative Performance Analysis for Irreversible Otto, Miller and Atkinson Cycles

Finite-time thermodynamic models for an Otto cycle, an Atkinson cycle, an over-expansion Miller cycle (M1), an LIVC Miller cycle through late intake valve closure (M2) and an LIVC Miller cycle with constant compression ratio (M3) have been established. The models for the two LIVC Miller cycles are first developed; and the heat-transfer and friction losses are considered with the effects of real...

Alternative Approach for predicting the performance of Irreversible Otto Cycle

The performance of an air-standard Otto cycle with variation of cycle peak temperature and variable specific heats of working fluid is analyzed. The relations between the power output and the compression ratio, between the thermal efficiency and the compression ratio, as well as the optimal relation between power output and the efficiency of the cycle are derived by detailed numerical examples....

THE EFFECT OF TYPE OF SPECIFIC HEATS RATIO OF WORKING FLUID ON THE THERMAL PERFORMANCE OF STANDARD OTTO CYCLE

In thermodynamic analysis of internal combustion engine, the specific heats of working fluid is considered to be constant. Due to specific heats are functions of operation temperature of cycle, this consideration cause to several errors in the thermal analysis. In this paper, standard Otto cycle with three various types of specific heats ratios has been analyzed numerically and effect of these ...
