Abstract
The slip effect on free convection of a Casson fluid past an infinite oscillating vertical
plate with constant wall temperature is investigated. It is used to characterize the
non-Newtonian fluid behavior. By introducing appropriate non-dimensional variables,
the resulting equations are solved analytically by using the Laplace transform
technique. The corresponding solutions for a Casson fluid without slip at the
boundary for λ → 0, a Newtonian fluid with slip for γ → ∞, and a Newtonian fluid in
the absence of slip for λ → 0 and γ → ∞ are obtained as limiting cases. The effect of
the Casson parameter is seen to suppress the velocity field. Also, the influence of the
slip parameter causes a decrease in the velocity field. Numerical results for velocity,
temperature, and Nusselt number are shown in various graphs and discussed for the
embedded flow parameters.
