This research aims to analyze the impact of various factors on the flow and transfer characteristics of Casson hybrid nanofluids in porous media.
Modeling the hybrid nanofluid composed of aluminum and silver nanoparticles in a Casson base fluid.
Transforming governing equations into nonlinear ordinary differential equations.
Solving the equations numerically using a fourth-order Runge–Kutta method with a shooting technique.
An increase in the Casson parameter reduces velocity profile due to enhanced shear resistance.
Brownian and thermophoretic parameters increase wall heat and mass transfer rates by approximately 10-20%.
The magnetic parameter reduces fluid velocity while increasing temperature gradients, resulting in a steeper thermal boundary layer.
Higher permeability enhances thermal dispersion but suppresses flow speed.
