Abstract: This study explores the impact of the Cattaneo–Christov heat and mass fluxes, viscous dissipation, and nonlinear thermal radiation on the stagnation point flow of electrically conductive Casson hybrid nanofluids over a porous material. Employing a similarity transformation, the nonlinear partial differential equations are reduced to nonlinear ordinary differential equations, which are then numerically solved using MATLAB’s bvp4c solver. The results highlight the influence of nanoparticle fraction on velocity, temperature, heat transfer, and drag forces, with hybrid nanofluids outperforming single nanofluids. Increased nanoparticle fraction improves particle interaction and thermal conductivity.
