The interaction of polymers with turbulent shear flows is examined. We focus on the structure of the elastic stress tensor, which is proportional to the polymer conformation tensor. We examine this object in turbulent flows of increasing complexity. First is isotropic turbulence, then anisotropic (but homogenous) shear turbulence, and finally wall bounded turbulence. The main result of this pap...

This paper is devoted to the analysis of heat transfer and Navier’s slip effects in a non-Newtonian Jeffrey fluid flowing past stretching/shrinking sheet. The nanoparticles, namely, Cu Al2O3 are used with water-based Prandtl number 6.272. Velocity flow assumed occur when characteristic size system small or pressure very small. By using similarity transformations, governing nonlinear PDEs turned...

This paper presents a linear stability analysis of natural convection in a horizontal layer of a viscoelastic nanofluid. The Oldroyd B model was utilized to describe the rheological behavior of a viscoelastic nanofluid. The model used for the nanofluid incorporated the effects of Brownian motion and thermophoresis. The onset criterion for stationary and oscillatory convection was derived analyt...

The rheological characteristics of liquids play an important role in the flow near dynamic contact lines, where deformation rates are extremely large. liquid line dynamics and free surface configuration curtain coating polymer solutions were experimentally studied using visualization to determine effect two characteristics: shear thinning extensional thickening. critical web speeds for heel for...
