“…Since Scovil and Schulz-DuBois [7] first proposed a three-level quantum heat engine model in 1959, many scholars have proposed quantum energy conversion devices and quantum thermodynamic cycles using various quantum systems as working fluids, such as particles in one-dimensional infinite potential well (OIPW) [8], relativistic particles in OIPW [9], spin system [10], resonance subsystem [11], quantum gas [12], etc. Using these common quantum working media (WM) and applying finite-time thermodynamics (FTT) [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], many scholars have studied the thermodynamic properties of quantum Stirling cycle [8], Carnot cycle [10,11,28], Diesel cycle [29], Brayton cycle [30,31], Otto cycle [32,33], etc. and got numerous meaningful results.…”

This paper establishes a quantum rectangular heat engine model by applying finite-time thermodynamics. The working medium is countless particles trapped in a one-dimensional infinite potential well. Taking into account heat leakage between the system and the outside, expressions for thermal efficiency (η), dimensionless power ( P ), and dimensionless efficient power ( Wep) of quantum rectangular heat engine are derived, and its optimal performance is studied. System performance P , η, and Wep are optimized firstly by taking the width ratio of the potential well as the optimization variable. The outcomes show that the relationship curve between P and η is a loop-shaped curve. With an increase in heat leakage coefficient, the optimal design range of the quantum rectangular heat engine becomes smaller. The relationship curve between the efficient power and width ratio of the potential well is parabolic-like. The relationship curve between Wep and η is a loop-shaped curve. The efficiency of the quantum rectangular heat engine at Wep max operating point is greater than that at Pmax operating point. Secondly, multi-objective optimization is applied with η, P , and Wep as optimization objectives by applying NSGA-II, and the optimal design scheme is achieved by applying TOPSIS, LINMAP, and Shannon entropy decision-making approaches. The smallest deviation index inferred by the Shannon entropy approach is 0.0269. The design scheme is closest to the ideal scheme. topics: finite-time thermodynamics; quantum rectangular heat engine (QRHE); power, multi-objective optimization, thermal efficiency and efficient power

“…Since the quantum heat engine (QHE) was introduced by Scovil and Schultz-Dubois in 1959 [1], many other publications have been published on this topic with different quantum working substances. The working substances that have been studied are two-level systems [2,3], many-level systems [4][5][6][7], harmonic oscillator systems [8][9][10][11], spin systems [3,12], etc. All the working substances used are in the microscopic realm where the principles of Quantum Mechanics strictly apply to QHE.…”

A study on the effect of heat leakage on power output, thermal efficiency, and reversibility rate in a relativistic quantum Lenoir engine has been conducted. Initially, we analogize the quantum working substance of the engine, a massless boson trapped in an infinite potential box with a movable right wall, as an ideal gas confined in a pistoned cylinder. Then, the total work, heat input, and heat output of each engine cycle which consists of isochoric, adiabatic expansion, and isobaric compression are extracted by applying the concept of quantum thermodynamics. Finally, power output, thermal efficiency, and reversibility rate of the engine are calculated for different variations of the heat leakage constant. The results are the relationship between several parameters which are expressed in the graph of thermal efficiency vs. compression ratio, graph of efficiency/normal efficiency vs. compression ratio, power output vs. efficiency, and reversibility rate vs. compression ratio. The conclusion is that an increase in heat leakage has an effect on reducing the efficiency and reversibility rate of the engine but does not affect its power output. This work will provide a new chapter for further research related to the use of the boson particle as a working substance in the quantum heat engine, especially the study of the heat leakage effect on engine performance.

“…Application of quantum principle in thermodynamical terms gives out clarity on fundamental problems, such as Maxwell's demon and the second law of thermodynamics (Kieu, 2006). Moreover, there have been several researches on the different cases that prove the compatibility of quantum mechanics applications into thermal engine terms (Ali et al, 2020;Belfaqih et al, 2015;Fernández, 2022;Muñoz & Peña, 2012;Singh, 2020;Singh & Rebari, 2020).…”

We study the performance of the quantum Lenoir engine using single-particle confined within the cubic potential. In 3D potential structure, particles degenerate into multiple states at identic energy level which occurs on the excitation state of the particles. Deliberating the degeneration effects, the confined particle has possibility to produce more energy efficiency as engine’s working substance. The particle is able to freely move in three directions of x, y, and z-axis simultaneously, which gives three degrees of freedom to the particle in the cubic potential. By limiting to two eigen states, a basic explanation to the condition of the particle was provided. The efficiency of 3D quantum Lenoir engine is better than the classical model of the Lenoir engine despite the similarity in the formulation. Moreover, we also consider the efficiency comparison between the 3D model, with some state modifications, and the 1D efficiency of the quantum Lenoir engine. As expected, degeneration of the particle’s states plays a role in the enhancement of the quantum Lenoir engine’s efficiency. Moreover, we also derived the power output of the 3D quantum Lenoir engine. Thus, this study clearly gives a sight of the performance of quantum Lenoir engine model in the 3D manner.
