流体最小能耗率原理的热力学基础

针对学术界一直存在争议的流体在运动过程中到底是遵循最大熵原理还是遵循最小能耗率原理或最小熵产生原理问题,以热力学理论为基础,分析最小熵产生原理和最小能耗率原理,同时澄清一些容易混淆的问题,指出:热力学中的基本原理、基本概念同样适用于流体运动;流体在运动过程中遵循最小能耗率原理或最小熵产生原理。

Principle of the minimum rate of energy dissipation for fluid based on the theory of thermodynamics

It is still being debated whether the motion of fluid follows the principle of minimum entropy production,the principle of the minimum rate of energy dissipation,or the principle of maximum entropy.This paper further analyzes the principle of the minimum rate of energy dissipation and the principle of minimum entropy production and clarifies some confusing issues based on thermodynamics theory.It is pointed out that the basic principles and concepts of thermodynamics can also be applied to the motion of fluid and that the motion of fluid follows the principle of minimum entropy production or the principle of the minimum rate of energy dissipation.
