Numerical Investigation of Joule Heating and Suction Effects on MHD Casson Nanofluid Flow over Exponential Stretching Sheet with Thermal Radiation and Chemical Reaction.

Résumé

The main part of the current examination is to forecast the consequence of the simultaneous incorporation of joule heating, radiation absorption with chemical reaction on Casson fluid flow across an exponentially stretching surface under the influence of various flow parameters. The resulting partial differential equations are transitioned into ordinary differential equations by employing a suitable similarity transformation. The resultant equations are computed numerically using MATLAB bvp4c built-in technique. In order to justify the precision of the numerical method used, the numerical values obtained in a constrained scenario are correlated with the outcomes existing in the literature. The impacts of multifarious dimensionless parameters on velocity profile, temperature and concentration distributions are illustrated graphically. The effect of involved parameters on skin friction coefficient, Nusselt number and Sherwood number are tabulated. The findings are evaluated for essential industrial and technical characteristics such as Nusselt numbers, temperatures, skin frictions, and velocity. The Combined influence of joule heating ,radiation absorption with the incorporation of an exponential parameter on the flow field is trailblazing since joule heating and the radiation absorption skyrockets the temperature, but on the contrary, chemical reaction depreciates the temperature.
