火用传递的普遍性和一般描述

Universality and generic description of exergy transfer

在阐述火用传递现象的普遍性与同一性,及其物理本质的基础上,探讨火用传递问题的研究思路,即以势场为载体寻求对火用传递过程共性的统一描述。对火用传递的无量纲准则、通用火用传递方程及普遍化火用传递方程等3种已有的火用传递过程的一般描述加以分析比较,并讨论了目前引人关注的场协同强化传递过程的火用传递实质,从而指出多势场协同作用下的火用传递问题的普遍存在及研究该类问题的必要性。

The universality, identity and physical essence of the exergy transfer phenomenon are demonstrated to seek a generic description for exergy transfer process using the field as carrier. The three existing generic descriptions for exergy transfer process, including dimensionless formula, the general exergy transfer equation and the universal exergy transfer equation are analyzed and compared. The exergy transfer essence of the transfer process intensified by field cooperation is discussed. The universality of exergy transfer with multi-field cooperation and the necessity of study on this issue are suggested.
