Investigation of Mixed Convective Stagnated Flow of Casson Nanofluid Past an Exponentially Stretching Sheet, using the Darcy - Forchheimer Model

Rekha Devi, Shilpa Sood

Abstract: This research uses the Darcy-Forchheimer model to analyze steady magneto hydrodynamics (MHD) boundary layer flow with mass and heat transport of Casson nanofluid over an exponentially stretched sheet in a porous medium with mixed convection. Additionally, consideration is given to how the transfer of the heat and the concentration of nanoparticles have been impacted by Brownian motion and thermophoresis. A method known as similarity transformation may be used to translate controlling partial differential equations into ordinary differential equations. The mathematical system of equations is solved by utilizing an inbuilt solver of MATLAB. Investigations have been done into how dimensionless parameters affect flow, heat transmission, and nanoparticle concentration. To investigate many dimensionless parameters impacts on concentration, velocity, and temperature, graphs were plotted and explained.
