Unsteady Stagnation-Point Flow of a Viscoelastic Fluid in the Presence of a Magnetic Field

الملخص EN

The unsteady two-dimensional stagnation point flow of the Walters B' fluid impinging on an infinite plate in the presence of a transverse magnetic field is examined and solutions are obtained.

It is assumed that the infinite plate at y=0 is making harmonic oscillations in its own plane.

A finite difference technique is employed and solutions for small and large frequencies of the oscillations are obtained for various values of the Hartmann's number and the Weissenberg number.
