Performance analysis of relativistic quantum lenoir engine with two state single fermion particle system in a one dimensional potential box / Yuni Setiasari

Abstrak
The Lenoir engine features a simple cycle process that represents one of the earliest realizations of a real heat engine. However like other classical heat engines it has a low efficiency. Implementing a quantum system is essential to enhance the efficiency of heat engines. In this study a two-state single fermion particle system confined in a 1D potential box is chosen as the model for a quantum Lenoir engine. The research method used is analytical employing a modified analogical model. The system s energy eigenvalues obtained from the Hamiltonian of the Dirac equation describe the process and yield thermodynamic quantities within the Lenoir cycle. The result of this study indicates that the efficiency formulation of the relativistic quantum Lenoir engine aligns with the classical system rsquo s formulation with the Laplace constant confirmed through statistical analysis to have a value of 2. From a comparative analysis it is found that the relativistic system yields higher efficiency than the classical one. However the non-relativistic system achieves higher efficiency at the same compression ratio. The efficiency of the system is proportional to the value of the Laplace constant. Furthermore the efficiency of the quantum Lenoir engine can be improved by increasing the energy level of the system at the end of the compression process by controlling the ground state as the initial state.
