This study explores using hybrid nanofluids to improve water quality by enhancing heat transfer and substance decomposition. Nanofluids effectively remove pollutants, optimise transfer, control pollution sources, regulate fluid dynamics, which can lead efficient management in systems. Thus, the present research examines flow of an unsteady Al2O3-Cu/water nanofluid near stagnation region a porous medium, considering discharge concentration convective boundary conditions. Governing equations ordinary differential are obtained similarity transformations. The BVP4C solver MATLAB is employed expose dual solutions. volume fraction copper suction/injection parameter unsteadiness collectively contribute delay layer separation. Increasing values , enhances transfer. When sheet shrunk between range has higher thermal than nanofluid. Moreover, increment raises skin friction coefficients mass diffusion rates. Stability analysis reveals that first solution stable while second one unstable.

The investigation of the nonlinearly expanding surface using Casson model has been conducted, with a focus on unique mixture known as hybrid nanofluid. This specific nanofluid consists blood suspended copper and Al 2 O 3 oxide. distinct shape nanoparticles enables swift mobility within nanofluid, accelerating their movement. We derived novel set similarity transformations, where variable is dimensionless appears in formulation function all independent variables. Runge-Kutta Fehlberg 4–5 th methodology was employed to numerically solve modified equations. In prior research papers, Homotopy perturbation Sumudu transform method (HPSTM) utilized derive analytical solution solely for momentum equation. However, this current study, applied coupled heat equations resulting an innovative that not previously explored. Comparison numerical results demonstrates precision present work. impact components thermal velocity plots explained.
