摘要
过增元基于质能方程提出了热质的概念.在非平衡热力学中,存在最低能量耗散原理,根据该原理可以导出热传导,扩散及粘性流动等不可逆输运过程的方程式.当采用热质模型对传热现象进行描述时,发现热质的运动也满足最小作用量原理:最低热质能耗散原理,根据该原理可以推导得出热质运动的动量守恒方程。
The concept of thermal mass was represented by Guo based on the theory of relativity. In irreversible thermodynamics there is the principle of minimum energy dissipation form which the transport equations including heat conduction,diffusion and viscosity can be derived.It is found that the transfer of thermal mass also satisfies the principle of minimum thermal mass energy dissipation, and from which the momentum equation of thermal mass can be derived.
