Abstract
This paper focuses on the phenomenological law of energy and mass transfer and accordingly analyzes the diffusive mechanism of heat flow,mass flow,workflow,and momentum flow in the conservation equation;the synergic mechanism of thermodynamic force in the synergy equation;and the dissipation mechanism of thermodynamic flow in the equilibrium equation.The synergic relations among heat,mass,and work transfer,as well as the power consumption of the fluid,were revealed by investigating the interaction between multiple physical fields.The transfer losses and efficiencies of heat,mass,work,and kinetic energy were proposed by studying the energy and mass dissipation in the transport process.Based on synergy and dissipation analysis,the macroscopic energy and mass transport theory was finally framed by presenting a unified energy and mass transfer equation set.
