Abstract: The slip flow and nonlinear radiative heat transfer of suspended nanoparticles due to a rotating disk is analysed in the present work. Two types of nanoparticles namely copper and aluminium oxide and water is treated as base fluid. Suitable similarity transformations are used to reduce the nonlinear partial differential equations to ordinary differential equations. Flow and heat transfer characteristics are computed by numerical technique Runge-Kutta-Fehlberg-fourth and fifth order method. Further, the skin friction coefficient and Nusselt number are presented and examined for pertinent parameters. It is noticed that the higher velocity slip parameter decreases the radial and azimuthal velocities. Also, the rate of heat transfer enhances when the nanoparticle volume fraction increases.
