The impact of coupled stress casson nanofluid-flow over a stretching surface will be examined in this paper. fundamental controlling PDE are transformed using the stated similarity transformation into pair coupled, non-linear ODE, one for velocity and other temperature distribution. modeled flow problem?s approximate analytical solution was discovered approach. Graphs used to illustrate effects...

The relaxation dynamics of a rubbed polystyrene (PS) surface have been characterized using infrared-visible sum frequency generation spectroscopy (SFG). The SFG results were compared with previous relaxation of retardation measurements, and the results show that the rubbed PS surface has the same T(g) as the bulk where T(g) is defined as tau(T(g))=5 s, however, the surface has a lower activatio...

We investigate the transient viscoelastic behavior of weakly strain-hardening fluids in filament stretching devices during uniaxial elongation and following the cessation of stretching. The numerical results are compared with experimental observations on a concentrated shear-thinning polystyrene solution which is well characterized by a multi-mode Giesekus model. The finite element computations...
