Electrically MHD Casson nanofluid flow and entropy exploration under the influence of the viscous dissipation, radiation, and higher-order chemical reaction

Abstract

Abstract The current study aims at studying the viscous dissipation and chemical reaction of higher-order Casson nanofluid flow and entropy exploration along with MHD and electric field influences. The PDE guiding the model is transformed into nonlinear ODE by applying adequate similarity transformations. Further, the equations are worked out using the Keller Box method. The influence of several parameters β , H a , E r , K r , N t , N b , S c , E c , Pr , R d is observed by constructing velocity, temperature, and concentration graphs using MATLAB. It is observed that entropy shows a rising tendency in the case of radiation parameter, Eckert number, decays for Casson parameter, temperature raises for radiation, Eckert parameters, and decays for Casson parameter. Velocity profiles decay for the Casson parameter. Also, local parameters skin friction, Nusselt number, and Sherwood numbers are calculated for Casson parameter, which is a function of Hartmann, number, Brownian motion parameter, thermophoresis parameter, which is a function of electric field parameter.
