Hybrid nanofluid, prepared with copper and silver as nanoparticles and as common fluid, entropy generation, flow and heat transport features within the closed chamber by captivating radiation and magnetic field are numerically investigated in this analysis. The resulting dimensionless equations are numerically evaluated by utilizing finite difference method. The variations in the scatterings of isotherms, streamlines and entropy generation with diverse values of radiation parameter , volume fraction of parameter of silver nanoparticles Prandtl number , Rayleigh number , volume fraction of parameter of copper nanoparticles and magnetic parameter have scrutinized which are schemed through graphs. The sketches of Nusselt number with respect to these parameters are also portrayed through plots. The outcomes of this investigation indicate that temperature gradient of copper nanoparticles is lesser than the silver nanoparticles. Rate of heat transfer augments from 4.8 to 14.5% in the case of silver nanoparticles of volume fraction 0.05 that are suspending into the base fluid, whereas heat transfer rate rises from 4.8 to 11.3% in the case of copper nanoparticles of volume fraction 0.05 that are suspending into the base fluid.
