Jaynes的MaxEnt、定常流系统和最大熵产生原理

Jaynes' MaxEnt, Steady State Flow Systems and the Maximum Entropy Production Principle

Robert K. Niven

摘要:

Jaynes的最大熵(MaxEnt)原理最近被用于给出“最大熵产生”(MEP)原理的条件局部推导,该原理指出具有固定流量或梯度的流动系统将收敛到热力学熵的最大产生的稳定状态(R.K. Niven,Phys. Rev. E,出版中)。该分析提供了平衡热力学MaxEnt公式的稳态模拟,适用于许多稳态复杂流动系统。本研究探讨了物理系统的分类,重点是在MaxEnt的约束条件的选择。讨论澄清了平衡,流体流动,源/汇,流/反应和其他系统之间的区别,导致评估的应用MaxEnt的稳态流和反应系统。

英文摘要:

Jaynes' maximum entropy (MaxEnt) principle was recently used to give a conditional, local derivation of the ``maximum entropy production'' (MEP) principle, which states that a flow system with fixed flow(s) or gradient(s) will converge to a steady state of maximum production of thermodynamic entropy (R.K. Niven, Phys. Rev. E, in press). The analysis provides a steady state analog of the MaxEnt formulation of equilibrium thermodynamics, applicable to many complex flow systems at steady state. The present study examines the classification of physical systems, with emphasis on the choice of constraints in MaxEnt. The discussion clarifies the distinction between equilibrium, fluid flow, source/sink, flow/reactive and other systems, leading into an appraisal of the application of MaxEnt to steady state flow and reactive systems.
