Keller Box procedure for stagnation point flow of EMHD Casson nanofluid over an absorbent stretched electromagnetic plate with chemical reaction

Abstract

In the present research, the stagnation point flow of EMHD Casson nanofluids over a stretchable electromagnetic plate is considered. Flow over the Riga plate is considered to analyze the Electromagnetic influences on fluid flow. Also, permeability, radiation, chemical reaction and heat source attributes are considered in this study. The guiding equations of the problem are transformed to nonlinear ODE using suitable similarity transformations. The numerical investigation of the flow is studied by implementing the Keller Box procedure using MATLAB. Validation of the numerical method is analyzed by comparing it with the previous studies. Also, calculated numerical observations of the local Nusselt and Sherwood parameters are of interest. An increase in the velocity outlines is detected for augmented observations of modified Hartmann number and unlike trends are noted for Casson, permeability, Prandtl number and suction factors. Temperature enhancement is witnessed for radiation, heat source, thermophoresis, Brownian diffusion and Biot number cases. Opposite trends are perceived in the case of suction constant. Concentration profiles are increasing for the alterations of thermophoresis parameter and declined in case of radiation, heat source, Brownian diffusion and Lewis number.
