Abstract
The present work addresses flows in ducts of different shapes. The fully developed entry profile for the axial velocity is found for the case of viscoplastic materials (Bingham plastics) and viscoelastic fluids (polymer melts) which obey an integral constitutive equation of the K-BKZ type. Several geometries are studied ranging from a square duct to an eccentric annulus. The results are given in generalized form as a function of flow rate vs. pressure drop for different values of the dimensionless parameters.
