Interaction between a complex fluid flow and a rotating cylinder

Abstract

The flow of a thixotropic Bingham material past a rotating cylinder is studied under a wide range of Reynolds and Bingham numbers, thixotropic parameters, and rotational speeds. A microstructure transition of the material involving breakdown and recovery processes is modeled using a kinetic equation, and the BinghamPapanastasiou model is employed to represent shear stress-strain rate relations...
