Abstract
This chapter presents up-to-date theoretical results and correlations for the most important surfaces used in compact heat exchangers. Full-developed Nusselt numbers and friction factors are given for many continuous duct cross-sections, followed by a summary of entrance effects (developing flow), which give rise to increased Nusselt numbers and friction factors. Turbulent and transitional flow data for ducts are then given. Plate-fin surfaces, in a variety of forms, are by far the commonest of all compact types, being used for applications from oil refining to air conditioning; and some of the many semiempirical correlations are assessed. In particular, the offset strip fin (OSF) data and correlations are given critical attention, based on the theoretical results developed in previous. After a summary of the performance of perforated fins, a more in-depth assessment of louvered and offset convex louvered fins is presented. Pressed-plate surface performance correlations are then given, followed by considerations of the performance of printed circuit channels and microchannels. The chapter ends with a brief discussion of porous and sintered surfaces for which, it is argued that no consistent methodology is yet in place for performance assessment.
