非平衡系统中的熵产生与能耗散函数

Entropy production & energy dissipation function in a non-equilibrium system

从普遍的热力学方程出发,导出了粘性多组分流体有外力场存在时的熵产生和能耗散函数的一般表达式,通过对具体过程的分析讨论,指出:能耗散函数在存在体积力的情况下,不具有普适性。

This paper develops on the basis of general thermodynamic formulae the common expression of entropy production and energy dissipation function of viscous multicomponent fluids with external forcefield, and points out through analysis of the process that with volume force,energy dissipation function is not universally adaptive.
