Abstract
This chapter amplifies the elements of compactness introduced in Chapter 1, and develops them to produce equations that can be used firstly, for sizing a given exchanger side and secondly to enable comparisons to be made between surfaces, each for a given thermal specification. The key equation developed is the core mass velocity equation in its two forms: for conventional performance descriptors of Colburn j and Fanning friction f factors; and for fully developed laminar flow in terms of Nusselt number and the product fRe. The analysis is further developed to provide aids to surface selection in the form of a dimensional (m−1) operating parameter Po which is wholly determined from the thermal and pressure drop specification for the side considered. The method of surface comparison (retaining the option to vary the hydraulic diameter) then encompasses both face area and volume (or weight). Some typical surfaces are compared on both test and common hydraulic diameters.
