Simulations of Johnson-Segalman viscoelastic fluids flows in shear-thinning regime

نویسندگان

چکیده

Abstract This paper presents selected numerical simulations performed using Johnson–Segalman model with specific setting of the convected derivative resulting in shear-thinning behavior model. The results are compared generalized Oldroyd-B model, which is typically used to simulate viscoelastic flows. Both models solved an in-house finite-volume solver on structured grid simulating steady flow three-dimensional axisymmetric channel smooth contraction. presented here focus recirculation behind contraction and structure forces emanating from stress tensor.

Linear instability of planar shear banded flow of both diffusive and non-diffusive Johnson-Segalman fluids

We consider the linear stability of shear banded planar Couette flow of the JohnsonSegalman fluid, with and without the addition of stress diffusion to regularise the equations. In particular, we investigate the linear stability of an initially onedimensional “base” flow, with a flat interface between the bands, to two-dimensional perturbations representing undulations along the interface. We d...

Planar Unsteady Flows of Incompressible Heat Conducting Shear Thinning Fluids

It is evident that behaviour of many fluids varies with varying temperature. We present mathematical properties of unsteady planar flows of shear thinning incompressible fluids where the change of the temperature influences the viscosity, which is at the same time shear thinning (power law fluids with power law index r − 2 < 0). Contrary of [2] (where a threedimensional flow is studied for 9/5 ...

Regularity of flows and optimal control of shear-thinning fluids

We study optimal control problems of systems describing the flow of incompressible shearthinning fluids. Taking advantage of regularity properties of the flows, we derive necessary optimality conditions under a restriction on the optimal control.

Turbulent pipe flow of shear-thinning fluids

Direct numerical simulation of the weakly turbulent flow of non-Newtonian fluids is undertaken for two different generalised Newtonian rheology models using a spectral element-Fourier method. Results for a power law (shear-thinning) rheology agree well with experimentally determined logarithmic layer correlations and with other previously published experimental work. As the flow index becomes s...

Numerical investigation of thermal mixing of shear thinning fluids in one-way opposing jets

In recent years, impinging streams have received increasing interest for their high efficiency in heat and mass transfer. This numerical study was conducted to investigate flow and heat transfer characteristics of one-way opposing jets of non-Newtonian fluids. Effects of Reynolds number impinging angle, momentum ratio and flow behavior index on mixing index were evaluated. The results showed im...
