A continuum mechanical model is presented to analyze the negative electrorheological responses of a particle-liquid mixture with the suspended micro-particles undergoing Quincke rotation for both Couette and Poiseuille flow geometries by combining particle electromechanics and continuum antisymmetric/couple stress analyses in the zero spin viscosity limit. We propose a phenomenological polariza...

The topic of this paper is the peristaltic motion a non-Newtonian Jeffrey fluid with couple stress across porous medium inside horizontal conduit. unit strained by uniform magnetic field. It taken into account effects viscous dissipation, internal heat generation, and radiation. This approach solves equations momentum, temperature, velocity. numerical formulas for axial velocity, velocity are c...

Sand production is a complex phenomenon caused by the erosion of borehole walls during extraction hydrocarbons. In this paper, sanding process in typical Thick-Walled Hollow Cylinder (TWHC) test numerically simulated. The main objective study to model particulate mechanism sand granular assemblies with different bonding conditions and examine effects parameters such as stress level cavity size ...

Viscoelastic liquid sheet of couple-stress type streaming with relative motion into an inviscid gas through porous molium is studied theoretically and quantitatively in this project. To derive the differential equations that describe liquids, gases, electric field, we linearized governing continuity, Maxwell’s quasi-static approximation, appropriate boundary conditions at two interfaces. Then u...
