Abstract

The present paper investigates the impacts of heat transfer and magnetic field on the boundary layer flow of Casson fluid over a linearly stretching sheet. The researchers have introduced analytical and numerical solutions for the momentum and energy equations by transforming the equations into the system of ordinary differential equations with the aid of the similarity transformations technique. The velocity and temperature profiles for pertinent constraints like Casson fluid constraint, Chandrasekhar number, Prandtl number, and thermal conductivity are presented through graphs. The influence of the wall shear stress and the Prandtl number increases while the boundary layer thickness decreases. Further, the effects of the Casson fluid constraint on the local skin friction and thermal gradient are studied and the outcomes are presented in tabular form. It is also observed that increase in Casson fluid constraint and Chandrasekhar number the local skin friction coefficient also rises at the wall but decreases in the temperature at the wall. The outcomes revealed that the analytical method had a good agreement with the numerical solutions obtained through MATHEMATICA software. The current study has applications in the processing of magnetic materials and the extraction of crude petroleum from oil-based products.
