摘要

自然界发生的热量传递、分子扩散、导电等现象具有一定的相似性,它们均可被称为广义流动.文章基于这种相似性,对过增元等针对传热过程提出的(火积)理论进行了推广,定义了积、积流、积耗散等概念.针对只有一种广义流动和存在两种广义流动的系统,指出了在该类系统中可以发展积原理的条件,并在满足相应条件的系统中得到了积损失极小值原理、积耗散极值原理和最小广义流阻原理.

关键词:

Some natural phenomena, such as heat transfer, molecular diffusion and electricity conduction, are very similar to each other to some extent. They all could be treated as generalized flows. Based on this kind of similarity, in this paper we generalize the theory of entransy, and define the concepts of potential entransy, potential entransy flux, and potential entransy dissipation. In the system where there is only one kind of generalized flow or two kinds of generalized flows, the conditions under which we can develop the principles of potential entransy are introduced. Furthermore, the minimum principle of potential entransy loss, the extremum principle of potential entransy dissipation and the generalized minimum flow resistance principle are developed and discussed.

Keywords:

generalized flow /
potential entransy /
minimum principle of potential entransy loss /
extremum principle of potential entransy dissipation
