This paper aims to provide a new design considering compressive force application in the MR fluid andimprove its braking torque by optimizing it. According current study, compressing region will increase compared no compression. The area covered an existing model of conventional disc brake is taken into consideration for unique operate shear and compression mode, required given hydraulic pressu...

We discuss the nonlinear rheology of dense colloidal dispersions at the glass transition. A first principles approach starting with interacting Brownian particles in given arbitrary homogeneous (incompressible) flow neglecting hydrodynamic interactions is sketched. It e.g. explains steady state flow curves for finite shear rates measured in dense suspensions of thermosensitive core-shell partic...

Network modeling is used to study the flow in porous media of Ellis and Herschel–Bulkley fluids, which model a large group of time-independent non-Newtonian fluids. Previous work is extended to include yield-stress and shear-thickening phenomena. We use two topologically-disordered networks representing a sand pack and Berea sandstone. Analytical expressions for the volumetric flow rate in a si...

Following recent works of several authors like Huilgol, Bhattacharya etd. and Javadpour et al., this paper is to contribute further to the literature of axial flow in a rotational coaxial rheometer. We consider axial flow of Herschel Bulkley mode1 between two concentric cylinders with the inner one rotating, while the outer cylinder is held stationary. An attempt has been made to direct the...

The present study investigates extrusion processing of unfoamed and foamed cocoa butter (CB) crystal-melt suspensions (CMSs) with varying crystal volume fraction ΦSFC. Capillary rheometry derived flow curves were fitted the Herschel–Bulkley–Papanastasiou (HBP) model, yield stress to wall shear ratio τ0/τw CB CMSs was compared for various Foamed behaved fluidlike ΦSFC≤11.9% according a brittle p...

Thin films consisting of polymer solutions are typically produced through a combination extrusion and shearing processes, where the anisotropic, non-Newtonian solution is deformed subjected to thermal treatment. This paper investigates polymeric thin by studying channel flow rheology that experience yield stress. The material described transversely isotropic fluid (TIF) model, which contains be...

Abstract The rheological properties of cement pastes prepared using kenaf-plant cellulose microfibers (CMFs), which was incorporated for the purpose internal curing, were investigated. main test variables are length and mass fraction CMFs. CMFs lengths 400 ?m 5 mm included in mixtures at 0.3, 0.6, 1, 2 wt.% cement. Dry CMF particles wetted with water to fiber saturation point vacuum filtration ...

We examine theoretically the spread of a jet impacting on circular disk and hydraulic jump viscoplastic fluid Herschel–Bulkley type. The depth-averaging approach is employed in supercritical region, subcritical flow assumed to be inertialess lubrication treated as shock, where balance mass momentum established radial direction, including effect surface tension across jump. show that, contrast N...
