Chemically radiative and magnetised Casson nanofluid due to Arrhenius kinetics with heat source/sink

The current investigation aims to study the Magnetohydrodynamics (MHD) Casson nanofluid model to simulate the thermo-solutal-free convection chemically with heat source/sink and radiation. The present flow situation is driven by Arrhenius kinetics in the energy equation. The considered flow situation is reduced via similarity transformations and further solved numerically by the Runge-Kutta with shooting scheme. The flow features of velocity, energy, and concentration are derived, and the results are presented through graphs.
