The focus of the current study is to investigate the influence of thermal radiation, magnetohydrodynamics, viscous dissipation, and convective boundary conditions along with velocity slip effects on \(\left(ZnO{-}Ti{O}_{2}/PG\right)\) hybrid nanofluid towards a nonlinear radially stretching sheet. Moreover, brick and needle-shaped nanoparticles of Zinc oxide ( \(Zno\) ) and Titanium dioxide \((TiO_2)\) are submerged in propylene glycol for a realistic shape factor influence. A suitable similarity transformation is utilized to transform the nonlinear governing partial differential equations into ordinary differential equations, which are then solved numerically. The impact of significant physical quantities on the velocity profile and temperature distribution is depicted through graphs. Furthermore, the bar charts are drawn to see the influence of significant physical quantities on skin friction coefficient and Nusselt numbers. The important results of this study are as follows: The lowest velocity and least temperature are found for needle-shaped \((ZnO{-}Ti{O}_{2}/PG)\) hybrid nanofluid while, the fastest velocity, and highest temperature are noted for bricked-shaped \((ZnO/PG)\) nanofluid. The highest surface drag and maximum rate of heat flux are recorded for needle-shaped nanoparticles in \((ZnO{-}Ti{O}_{2}/PG)\) hybrid nanofluid. Our comparison investigation indicates that the best option for producing cylindrical components is needle-shaped nanoparticles in a \((ZnO{-}Ti{O}_{2}/PG)\) hybrid nanofluid.
