Exact Solutions for Chemically Reactive Species in Casson Fluid past an Exponentially Accelerated Surface with Newtonian Heating in the Presence of Thermal Radiation

Abstract An exact analysis of heat transfer accompanied by mass transfer flow of a Casson fluid past an exponentially accelerated infinite vertical plate with Newtonian heating in the presence of radiation is presented here. The governing coupled linear partial differential equations are transformed into linear ordinary differential equations by using non-dimensional variables. The resulting equations have been solved analytically using Laplace-transform technique. Closed form solutions are obtained for velocity, temperature and concentration profiles for different governing parameters. The paper intends to show unique results for a combination of heat transfer and chemical reaction in a Casson fluid flow. Expressions for shear stress in terms of Skin friction, the rate of heat transfer in terms of Nusselt number and mass transfer in terms of Sherwood number are also obtained. All the numerical results with various values of embedded flow parameters are analyzed graphically and their physical aspects are discussed in detail.
