气体的最佳热力学过程

Optimal Thermodynamic Processes For Gases

Alexei Kushner, Valentin Lychagin, Mikhail Roop

摘要:

本文考虑气体平衡热力学中的一个最优控制问题。气体的热力学状态由接触热力学空间中的勒让德子流形给出。使用庞特里亚金的最大值原理,我们发现这个子流形上的热力学过程,使气体最大化的功能。对于理想气体,这个问题被证明是可积的刘维的意义和它的解决方案是通过行动的角度变量。对于作为理想气体扰动的实际气体,给出了渐近积分。

英文摘要:

In this paper, we consider an optimal control problem in equilibrium thermodynamics of gases. Thermodynamic state of the gas is given by a Legendrian submanifold in a contact thermodynamic space. Using Pontryagin's maximum principle we find a thermodynamic process on this submanifold such that the gas maximizes the work functional. For ideal gases, this problem is shown to be integrable in Liouville's sense and its solution is given by means of action-angle variables. For real gases considered as a perturbation of ideal ones, the integrals are given asymptotically.
