Abstract: The current study deals with the steady flow of a nanofluid under the influence of magnetic field, heat radiation with prescribed external flow of mixed convective boundary layer flow over a vertical circular cylinder. The radiative heat loss is modelled by Rosseland approximation. Similarity variables are used to remodel the partial differential equations into ordinary differential equations. The remodeled equations are solved numerically by the technique of Runge-Kutta –Fehlberg with shooting. During this study nano particle Alumina(Al2O3) with water and kerosene as the base fluids is studied. For Alumina-water and Alumina-kerosene, nanofluid the nanoparticle volume fraction influences on velocity temperature are presented graphically. The impact of pertinent parameters on velocity and temperatures are resolute and details are mentioned through several plots. The coefficient of skin friction and local Nusselt number for different pertinent parameters are discussed and presented graphically.
