Stress singularities and the formation of birefringent strands in stagnation flows of dilute polymer solutions [PDF]
J. Non-Newtonian Fluid Mech. 157 (2009) 126-132, 2009 We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the ...

Unsteady stagnation point flow of a non-Newtonian second-grade fluid [PDF]
International Journal of Mathematics and Mathematical Sciences, 2003 The unsteady two-dimensional flow of a viscoelastic second-grade fluid impinging on an infinite plate is considered. The plate is making harmonic oscillations in its own plane.

Unsteady Reversed Stagnation-Point Flow over a Flat Plate [PDF]
World Academy of Science, Engineering and Technology 68 2012, 2013 This paper investigates the nature of the development of two-dimensional laminar flow of an incompressible fluid at the reversed stagnation-point. ". In this study, we revisit the problem of reversed stagnation-point flow over a flat plate. Proudman and Johnson (1962) first studied the flow and obtained an asymptotic solution by neglecting the viscous ...

Unsteady Separated Stagnation Point Flow of Nanofluid past a Moving Flat Surface in the Presence of Buongiorno's Model [PDF]
Journal of Applied and Computational Mechanics, 2021 This paper explores energy and mass transport behavior of unstable separated stagnation point flow of nanofluid over a moving flat surface along with Buongiorno’s model. Characteristic of Brownian diffusion and thermophoresis are considered. Additionally,

Spectral Quasi-linearization for MHD Nanofluid Stagnation Boundary Layer Flow due to a Stretching/Shrinking Surface [PDF]
Journal of Applied and Computational Mechanics, 2020 This article concentrates on the effect of MHD heat mass transfer on the stagnation point nanofluid flow over a stretching or shrinking sheet with homogeneous-heterogeneous reactions. The flow analysis is disclosed in the neighborhood of stagnation point.
