This article presents numerical investigation of heat transport, flow and entropy generation features of hybrid nanofluid, made up of Aluminum oxide, single – walled carbon nanotubes as nanoparticles and Ethylene glycol as base fluid, inside a square cavity. The resultant non-dimensional equations are numerically assessed by employing finite difference technique. The variations in the scatterings of isotherms, streamlines and entropy generation with diverse values of radiation parameter volume fraction of parameter of alumina nanoparticle Prandtl number Rayleigh number volume fraction parameter of single—walled carbon nanotubes and magnetic parameter have schemed through graphs. Rate of heat transfer augments from 8.2% to 17.6% in the case single—walled carbon nanotubes of volume fraction 0.05 are suspending into the base fluid, whereas, heat transfer rate rises from 8.2% to 12.4% in the case of alumina nanoparticles of volume fraction 0.05 are suspending into the base fluid.
