The present study explores the thermal and Joule heating effect of Casson nanofluid flow with chemical reaction over an inclined porous stretching surface. The results of heat source/sink, viscous dissipation, and suction are regarded. The new physical governing equations of partial differential flow equations are converted into nonlinear ordinary differential equations and are numerically resolved employing the implicit finite difference technique. The influence on velocity, temperature, and concentration fields of many flow variables are addressed. The numerical and graphical findings are defined for the numerous related attentiveness flow parameters. The empirical data reported are compared with the published outcomes.

The objective of this research is to explore the heat and mass transfer properties of an unsteady MHD natural convective Non-Newtonian, Casson fluid flow through a permeable vertical plate in the existence of Soret, Dufour, and chemical reaction. The aspects of heat and radiation absorptions are also factored in. Applications of the present study would be useful in magnetic material processing and chemical engineering systems. Mathematically, the flow field situation is expressed in terms of partial differential equations. The transformed flow-narrating partial differential equations of momentum as well as energy and species concentration were numerically solved using the finite element technique. Non-dimensional flow parameters were used to extract the numerical outcomes of velocity, temperature, and concentration, and the outcomes are envisioned graphically. The significance of the factors determining, Nusselt number, Sherwood number, and skin friction is also considered. The outcomes reveal that raising the permeability parameter causes the velocity to improve while enhancing the Casson parameter causes the velocity distribution to reduce.
