Abstract

The entransy is a new developed parameter that is effective in optimization of heat transfer. It can be used as an evaluation of the transport ability of heat. In this chapter, based on the energy conservation equation, the entransy balance equations for heat conduction and convective heat transfer are developed. The entransy dissipation extreme principle is developed. This extreme principle can be concluded into the minimum thermal resistance principle defined by entransy dissipation.
