“…The system used in this study is a 3D potential well containing one particle. This system has three degrees of freedom represented by three levels of state, namely k, l, and m. In a previous study, the system used is a 1D with one degree of freedom [8] and 2D with two degrees of freedom [19] represented by one and two-level of state, respectively.…”

“…system with different dimensions (1D [8], 2D [19], and 3D potential wells) are compared by substituting the same compression ratio value and the state of the particles from the ground state to the first excited state, it will produce a graph in Figure 4. If the value of the compression ratio is 0.3, then the efficiency value of the quantum Brayton engine for 1, 2, and 3 dimensions are 77.32%, 83.42%, and 85.71%, respectively.…”

A theoretical quantum Brayton engine research has been carried out using a potential box system to increase its thermal efficiency. The method applied in this research is a classical thermodynamics system model in the form of a piston tube containing a monatomic ideal gas analogous to a quantum model in the form of a potential box containing one particle. The efficiency formulation of the quantum Brayton engine obtained from this study is following the classical version. However, the efficiency value obtained on a quantum Brayton engine is higher when compared to its classic. It happens because the value of the Laplace constant owned by the Brayton quantum version is 3, while the classic version is 5/3.

“…The right wall of the potential box can move freely like a piston. The success of this method led to many other publications for other quantum cycles such as Brayton [4,6,[15][16][17], Otto [8,18,19], Diesel [7,20], Dual [21][22][23], Stirling [2,10,24], Ericsson [24], etc. These studies have not only focused on obtaining efficiency formulations of the cycles but have progressed to study power output, efficiency at maximum power output, reversibility rate, the effect of the presence of heat leakage [25,26], etc.…”

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.
