Abstract
We discuss properties of solutions of the Bingham flow equations for visco-plastic fluids through an eccentric annular cross-section. Particularly, we perform arguments which are not in favor of the well-known Szabo–Hassager’s conjecture that the rigid zone is confined by circles provided the eccentricity is small (J Non-Newtonian Fluid Mech 45:149-169, 1992).
