Abstract

The effectiveness of an unstable, incompressible, electrically conducting Casson fluid that spontaneously passes over a starched sheet of variable heat, mass movement, with a steady magnetic field, and chemical reaction field is examined in this paper. Using the appropriate similarity transformation to solve the governing equations of the flow model non-dimensional mathematically. As the magnetic parameter increased, it was observed that the velocity profile decreased while the thermal profile compacted. With an increasing electric field parameter and a decreasing unstable field parameter, the velocity profile has dropped. The magnetic field, Schmidt number, and electric field parameter increase the Skin friction coefficient while the Casson parameter decreases. Because of the rising Schmidt number, Brownian motion and thermophoretic characteristics, the local Nusselt number has decreased. Moreover, heat profile has decreased while the velocity profile has dropped in response to an augmenting magnetic parameter. While as higher Schmidt number reduces the thermal profile; however, it causes the thermophoresis, thermal radiation and Brownian motion characteristics to increase.
