Pressure drop during the flow of viscoplastic fluids through ducts
An equation of Rabinowitsch-Mooney type together with the corresponding relations for consistency variables has been adopted for an approximate calculation of pressure drop in flow of viscoplastic fluids through straight ducts. The suitability of the suggested procedure of calculation of pressure drop is demonstrated by the comparison of calculation results with the published analytical solution of flow of Robertson-Stiff fluid through an annulus and with numerical solution of flow of Bingham fluid through ducts of rectangular cross section.
