Entransy Dissipation Theory and Its Application in Heat Transfer [PDF]
, 2011 In this chapter, our recent work on the entransy dissipation theory and its application in heat convection and the heat exchanger design is reviewed. In that work, the thermodynamic basis of the entransy dissipation theory is established. It is shown that the entransy is a state variable and the second law of thermodynamics can be described by the ...

Application of entransy theory in the heat transfer optimization of flat-plate solar collectors [PDF]
Chinese Science Bulletin, 2012 The flat-plate solar collector is an important component in solar-thermal systems, and its heat transfer optimization is of great significance in terms of the efficiency of energy utilization. However, most existing flat-plate collectors adopt metallic absorber plates with uniform thickness, which often works against energy conservation. In this paper,
