Effects of MHD on the Unsteady Rotating Flow of a Generalized Maxwell Fluid with Oscillating Gradient Between Coaxial Cylinders

摘要

The aim of this paper is studied the effect of magnetic field on the unsteady rotating flow of a generalized Maxwell fluid with fractional derivative between two infinite straight circular cylinder .The velocity field and the shear stress are obtained by means of discrete Laplace transform and finite Hankel transform. The exact solution for the velocity field and the shear stress that have been obtained by integral and series form in terms of the generalized G functions and Mitting –leffer function .the graphs are plotted to show the effects of the fractional parameter on the fluid dynamic characteristics with MHD on the velocity and shear stress.
