Abstract
This chapter first deals with how ESF devices can be sized in a simple but effective way. A more accurate approach is then reviewed in which an ideal ESF (viscoplastic) model is used to gain direct and semi-iterative (CF) method) solutions of the governing equations of motion. A dimensional analysis approach in which an algorithm is used to account for non-ideal behaviour is then explained. The final section explains how the computational fluid dynamics (CFD) technique works and the unique advantages it offers.
