Boundary Value Problem, 30, 1-11. (Muhammad Imran Asjad (Mathematics /SSC), JCR LISTED (IF:0:642))https://escholar.umt.edu.pk/handle/123456789/3266The 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.enMathematicsCasson fluid; oscillating flows; free convection; velocity field; exact solutions; slip effectArticle
