Abstract
The rate of entropy generation, (S) over dot(G)'[W/mK], is examined both th eoretically and numerically for forced and mixed convection in a rectangula r duct heated at the bottom. Under fully-developed flow conditions (S) over dot(G)' is expressed in terms of relevant non-dimensional hydrodynamic and thermal parameters. Numerically, it is demonstrated that (S) over dot(G)' is a single, effective parameter to examine both thermal and hydrodynamic f ields and their variations.
