“…The particle would divide the energy to push the potential wall in three directions. The 1D model which has been carried out by Saputra (2021), the quantum Lenoir engines have higher efficiency than the classical Lenoir engines due to the value of its specific heat ratio. In their research, the particle in which is the working substance in their engine model is only able to expand at the x-axis.…”

“…where Ltotal is the total length change within one cycle, while v is the average velocity of the length to change (Saputra, 2021;Sutantyo et al, 2021). Since the 3D model is a cubic potential that expands and compresses simultaneously, the value of Ltotal on each axis should be the same…”

“…Lenoir engine is one of potentially merged to quantum engines model. Saputra (2021) has proven that the classical and quantum Lenoir engines are both similar in the way of efficiency formulation, but quantum Lenoir engines have higher efficiency because of its specific heat ratio. However, the efficiency of the 1D model is lower compared to 3D quantum engine models.…”

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.

We consider optimizations of Lenoir heat engine within a quantum dynamical field consisting of N noninteracting fermions trapped in multilevel infinite potential square-well. Fermions play role as working substance of the engine with each particle nested at different level of energy. We optimized this quantum heat engine model by analysing the physical parameter and deriving the optimum properties of the engine model. The model we investigated consists of one high-energy heat bath and one low-energy sink bath. Heat leakage occurs between these two bathes as expected will degenerate the efficiency of quantum heat engine model. The degeneration increased as we raised the constant parameter of heat leakage. We also obtained loop curves in dimensionless power vs. efficiency of the engine, which efficiency is explicitly affected by heat leakage, but in contrast for the power output. From the curves, we assured that the efficiency of the engine would go back to zero as we raised compression ratio of engine with leakage. Lastly, we checked Clausius relations for each model with various levels of heat leakage. We found that models with leakage have a reversible process on specific compression ratios for each variation of heat leakage. Nevertheless, the compression ratio has limitations because of the dQ/E > 0 after the reversible point, i.e. violates the Clausius relation.

Quantum Lenoir engine in the presence of minimal length

The eﬀect of minimal length for quantum heat engine systems is proposed. We use a system of trapped Fermi particles in an inﬁnite potential well. The thermodynamic cycle chosen is the reversible Lenoir cycle. We use both a single particle case and a multiparticle case. The result is that the minimum length increases the eﬃciency of the machine if the width of the potential well is inﬁnitely small, and the maximum value is obtained when the width of the potential well is close to zero.
