Abstract In this article, natural convection 3D magneto hydrodynamic flow and heat transfer of MoS2–Ag/ ethylene glycol-water (50–50%) hybrid Nano fluid along a vertical stretching surface in the attendance of variable thermal conductivity, non-linear thermal radiation and nanoparticle shape factor has been analyzed using Runge–Kutta Fehlberg fifth order (RKF 5) numerical method. The impact of changing different parameters and nanoparticles shape, named Bricks, Cylinders, Platelets and Blades on temperature and velocity distribution has been explored. Outputs demonstrate Lorentz force produced by increasing Hartman number (Ha) causes reduction in velocity profile. Increasing thermal radiation and shape factor caused increase in temperature profile and Nusselt number (Nu). The impact of hybrid nanoparticles on increasing Nusselt number is more than nanoparticle. Furthermore, validation of obtained results indicates the high accuracy of solving method employed in this paper.
