Numerical modeling of conjugate heat transfer on complex geometries with diagonal cartesian method, part II: Applications

Part I of this study discusses the diagonal Cartesian method for temperatur e analysis. The application of this method to the analysis of flow and conj ugate heat transfer in a compact heat exchanger is given in Part II. In add ition to a regular (i.e., Cartesian-oriented) fin arrangement, two complex fin arrangements are modeled using the diagonal Cartesian method. The press ure drop and heat transfer characteristics of the different configurations are compared. It is found that enhanced hear transfer and reduced pressure drop can be obtained with the modified fin arrangements for this compact he at exchanger.
