We investigated an axisymmetric unsteady two-dimensional flow of nonconducting, incompressible
second grade fluid between two circular plates. The similarity transformation is applied to
reduce governing partial differential equation PDE to a nonlinear ordinary differential equation
ODE in dimensionless form. The resulting nonlinear boundary value problem is solved using
homotopy analysis method and numerical method. The effects of appropriate dimensionless
parameters on the velocity profiles are studied. The total resistance to the upper plate has been
calculated.
