Rheological properties of aqueous suspensions (48 vol%) of zircon-alumina mixtures containing different amounts of polyelectrolyte as dispersant were studied. Slip casting in a plaster mold and pressure filtration at 8 MPa experiments were performed to correlate the rheological properties of the suspensions with the relative density of green casts. Flow curves fitted satisfactorily to the Casso...

In this manuscript, fractional modeling of non-Newtonian Casson fluid squeezed between two parallel plates is performed under the influence magneto-hydro-dynamic and Darcian effects. The model fractionally transformed through mixed similarity transformations. As a result, partial differential equations (PDEs) are to ordinary equation (FODE). current modeling, continuity satisfied while momentum...

The impact of the Caputo fractional derivative on unsteady mixed convention boundary layer flow Casson fluid is investigated. It evaluated via two different geometries which are plate and microchannel with oscillating motion. problems modelled using a set partial differential equations appropriate initial conditions. dimensional turned into dimensionless governing by relevant variables. obtaine...

We derive formulae which lend themselves to TQFT interpretations of the Milnor torsion, the Lescop invariant, the Casson invariant, and the Casson-Morita cocyle of a 3-manifold, and, furthermore, relate them to the Reshetikhin-Turaev theory.

It is known that if any prime power branched cyclic cover of a knot in S is a homology sphere, then the knot has vanishing Casson-Gordon invariants. We construct infinitely many examples of (topologically) non-slice knots in S whose prime power branched cyclic covers are homology spheres. We show that these knots generate an infinite rank subgroup of F(1.0)/F(1.5) for which Casson-Gordon invari...

Pulsatile flow of blood through mild stenosed narrow arteries is analyzed by treating the blood in the core region as Casson fluid and the plasma in the peripheral layer as Newtonian fluid. Perturbation method is used to solve the coupled implicit system of non-linear differential equations. The expressions for velocity, wall shear stress, plug core radius, flow rate and resistance to flow are ...

In current communication, the thin-film flow of Casson hybrid nanofluid consists copper and alumina nanoparticles that dissolved in carboxymethyl cellulose (CMC) plus water over an unsteady stretching porous sheet is elucidated. Using suitable similarity variables, resultant partial governing equations are turned into a set nonlinear ordinary differential equations. The Keller box approach then...

Abstract In this paper, we compared copper-engine oil Casson–Maxwell, Casson–Jeffrey, and Casson–Oldroyd-B binary nanofluids in a parabolic trough solar collector. Using appropriate similarity variables, the partial differential equations governing nanofluid flow were converted into ordinary equations. The resulting nonlinear systems solved using shooting method. numerical results presented gra...
