Exergy Transfer Analysis of Convection Heat Transfer

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. (C) 2007 Wiley Periodicals, Inc.
