Suction effect on the dynamics of EMHD casson nanofluid over an induced stagnation point flow of stretchable electromagnetic plate with radiation and chemical reaction

Abstract

This research examines the radiative characteristics of electromagnetohydrodynamic (EMHD) boundary layer flow with combined thermal transport properties on a reactive stretching surface using Casson nanofluid. The momentum, temperature, and diffusion equations' governing flow equations are reduced to dimensionless forms through variable transformations. The remedies to the resulting equations are numerically generated using the MATLAB bvp4c. Validation against prior research is carried out. The impact of emerging factors on velocity, temperature, concentration patterns, drag force coefficient, Sherwood number, and Nusselt number are graphically represented and in tables. It indicates that when Prandtl number, lower variables of Suction, and Casson parameters increases with a decline in velocity distribution, the contrasting trend enhancement is perceived for modified Hartmann number. In addition, an increment in the modified Hartmann number increases the rate of energy, mass flux, and friction. Conclusively, As Lewis number, Brownian motion, and chemical reaction rise, the thickness of the concentration boundary layer decreases on the stretching Riga surface.
