ABSTRACT: This paper investigates effects of Hall current on flow of unsteady magnetohydrodynamic (MHD)
axisymmetric second-grade fluid with suction and blowing over a sheet stretching exponentially
with radius. The governing non-linear partial differential equations describing the problem are
converted to a system of non-linear ordinary differential equations by using the similarity transformations.
The complex analytical solution is found by using the homotopy analysis method
(HAM). The existing literature on the topic shows that it is the first study regarding the effects of
Hall current on flow over an exponentially stretching sheet in cylindrical coordinates. The convergence
of the obtained complex series solutions is carefully analyzed. The effects of dimensionless
parameters on the radial and axial components of the velocity are illustrated through plots.
Also the effects of the pertinent parameters on the shear stress at the wall are presented numerically
in tabular form.
