Abstract

Experimental and computational results related to the flow of purely viscous non-Newtonian fluids exhibiting a yield stress are presented and discussed. A number of geometries and flow conditions have been analyzed representing both attached and separated flows of Bingham and Herschel-Bulkley fluids. The presence of a yield-stress is shown to significantly impact the flow characteristics, as compared to those in the case of a Newtonian fluid, in particular in the cases where separation of the flow would be expected.
