Exergy transfer analysis of convection heat transfer

Abstract

In this paper, based on the fundamentals of thermodynamics and heat transfer, an analysis is made of the exergy transfer of convection heat transfer. Some exergy transfer differential equations are derived under constant thermophysical property and uncompressible laminar flow in the convection heat transfer process. Taking one-and two-dimensional convection heat transfer as examples, respectively, the exergy functions are solved and calculated. Their results agree well with those results from thermodynamic analysis.

“…But with the further researching of energy transfer, it is found that the energy transferred will be different by its property or energy grade, whose effectiveness will vary with the process, and the whole energy can be divided into an exergy part and an anergy part. Many researchers found that knowing about the mechanism of this kind of energy transfer will be very important and significant for optimal system design, economical control, and high-efficiency energy-saving applications [15]. Since Soma [16] and Dunbar et al [17] put forward the concept of exergy transfer and its equation, the research on exergy transfer has gained some researchers' attention.…”
