理想费米气体狄塞尔循环效率的研究

Study on Efficiency of a Dissel Cycle of Ideal Fermi Gas

在分析了研究狄塞尔循环时需要考虑其量子效应的必要性以及该循环在实际社会生产中的广泛应用前景后,首先给出以理想气体为工作物质的狄塞尔循环的效率表达式,然后以理想费米气体为例,根据其状态方程及其热力学性质获得以理想量子气体为工作物质的狄塞尔循环的效率表达式,通过比较得出提高实际热机效率的主要途径.

At the beginning, the necessity of taking quantum effect into consideration when studying Diesel cycle is put forward, and the prospects of the cycle application to practical uses are noted. The expression of efficiency of Diesel cycle whose work substance is ideal gas is then given. The expression of efficiency of Diesel cycle whose work substance is ideal Fermi gas, considering the state equation and the thermodynamic properties of the quantum gas, is provided afterwards. It is shown through the comparison that heat engine efficiency is improved when Diesel cycle working under quantum degeneracy condition,
