Combined effect of radiation absorption and exponential parameter on chemically reactive Casson fluid over an exponentially stretching sheet

Abstract

The essence of the current examination is to predict the consequence of the simultaneous incorporation of radiation absorption and chemical reaction on Casson fluid flow across an exponentially stretching surface under the influence of various exponential order flow parameters. The regulating partial differential equations are transitioned into ordinary differential equations by employing a best-suited similarity transformation. The resultant equations are computed numerically using MATLAB bvp4c built-in technique. In order to justify the precision of the numerical method used, the numerical values obtained in a constrained scenario are correlated with the outcomes existing in the literature. The impacts of multifarious dimensionless parameters on velocity profile, temperature and concentration distributions are illustrated graphically. The effect of involved parameters on skin friction coefficient, Nusselt number and Sherwood number are tabulated. The Combined influence of chemical reaction and radiation absorption with the incorporation of an exponential parameter on the flow field is trailblazing since the radiation absorption skyrockets the temperature, but on the contrary, chemical reaction decelerates the temperature.
