Abstract: The current study analyses entropy generation induced by coupled forced convection and thermal radiation heat transfer, in circular tubes and for non-grey media. A laminar flow of over heated water vapour in the entrance region of the duct was investigated. A specially developed numerical model, based on the finite-volume technique, is used for the solutions of the governing differential equations. The radiative transfer coefficients are deduced by use of the gRay Tracingh method through S4 directions, in combination with the statistical narrow band correlated-k (SNBCK) model. The local entropy generation distributions as well as the overall entropy generation in the whole flow fields are analyzed. The developing of velocity and temperature fields is also presented in this study.
Keywords: Entropy generation, Coupled convection and radiation, SNBCK model, Non-grey gas.
