This work deals with the study of mass and heat transmission in nanofluid flow Powell-Eyring model over a sheet that is exponentially stretched motile microorganisms. Additionally, viscous dissipation radiation sources are considered. The governing expressions remodeled into nonlinear ordinary differential equations by implementing appropriate transformations. numerically computed using bvp4c technique via MATLAB. various parameters used to investigate explain depth velocity, thermal, nanoparticle volume fraction, microbe density profiles.

The hybrid nanofluids are crucial for enhancing heat transfer efficiency in different technological and industrial operations like nuclear reactor cooling, fuel cells, drug delivery systems, etc. Taking this factor into account, the current investigation focused on MHD Darcy–Forchheimer flow of water-based nanofluid (Cu-Al2O3) mono (Cu) past a stretched surface with injection/suction. Additionally, focuses analyzing consequences nonlinear thermal radiation consumption/generation. governing higher-order PDEs rehabilitated ODEs through suitable transformation process. Finally, we solve these equations using quantitative approach Bvp4c algorithm MATLAB visualize results tables graphs. Our study revealed that intensified magnetic field, porosity, injection/suction parameters suppress fluid velocity. is enhanced when intensifying radiation, nanoparticles volume fraction parameters.
