| Summary: | For entire heat transfer practitioners from the last ten years, heat transmission performance in cooling and heating applications has become foremost concern. Hence, research towards innovative heat transference fluids is enormously powerful and stimulating. This study examines flow and thermal management in axisymmetric magneto hydrodynamic Polyethylene glycol (PEG) based hybrid nanofluid flow induced by a swirling cylinder. Flow and heat transfer is analyzed and compared for PEG+ <italic>Cu</italic><sub>2</sub><italic>O</italic> + <italic>MgO</italic> and PEG+Graphene+ <italic>Cu</italic> + <italic>Ag</italic> hybrid nanofluid flow. Shooting technique (R-K 4<sup>th</sup> order) is applied to work out the flow equations numerically. Simulated results are demonstrated via graphs. The computational results are validated with the published research work and found a modest concurrence. The foremost outcome of this investigation is found to be the axial, swirl and radial velocities in hybrid nanofluid are observed to decay with improvement in Reynolds number, nanofluid volume fraction and magnetic parameter. Platelet shaped nanoparticle colloidal suspension exhibit more decaying axial, swirl and radial velocity compared to spherical shaped nanoparticle colloidal suspension. It is detected that heat transmission rate is higher in <italic>PEG</italic> + <italic>Cu</italic><sub>2</sub><italic>O</italic> + <italic>MgO</italic> Hybrid nanofluid compared with <italic>PEG</italic> + <italic>Graphene</italic> + <italic>Cu</italic> + <italic>Ag</italic> Hybrid nanofluid. For cooling purpose one can adopt PEG+<italic>Cu</italic><sub>2</sub><italic>O</italic> + <italic>MgO</italic> hybrid nanofluid.
