A numerical study of flow and heat transfer in compact heat exchangers

An accurate computational method for the calculations of flow and heat transfer in compact heat exchangers is developed in collaboration with the National Center for Supercomputing Applications. In this method, the unsteady Navier-Stokes and energy equations are solved. A linearly scalable performance of the code is achieved on the massively parallel CM5, demonstrating the capability of this method to solve large scale heat transfer problems. The heat transfer enhancement mechanisms and performance of parallel-plate fin heat exchangers are studied extensively. Geometry effects such as finite fin thickness and different fin arrangements have been investigated. The roles of individual enhancement mechanisms and their attendant effects on frictional loss have been quantified.
