Abstract This research article explores the effect of entropy generation through a non-linear radiative flow of viscous fluid of hybrid nanoparticles over a stretchable rotating disk. Mixed convection and slip conditions i-e velocities and thermal are examined. The examination is accomplished in aluminum oxide (Al2O3)-water and copper (Cu)-water nanofluids. Similarity transformations are utilized to reduce the governing problem into the nonlinear ordinary differential equations. Flow in the permeable medium is analyzed by assuming the Darcy-Forchheimer model. The impact of various parameters consisting of mixed convection parameter, porosity parameter, velocities as well as thermal slips parameters, stretching parameter, non-linear radiation parameter, and Reynolds number on radial velocity profile, tangential velocity profile and temperature profile are studied. Also, entropy generation and heat transfer rates have been analyzed in view of different parameters in the current study. The mathematical formulation is numerically solved by the bvp4c techniques
