Abstract This article examines unsteady axisymmetric flow of third grade fluid between two disks. Upper disk is being squeezed towards the lower porous disk. Electrically conducting fluid and convective boundary conditions are used. Heat transfer analysis is carried out in the presence of Joule heating, viscous dissipation and thermal radiation effects. Partial differential equations are reduced into ordinary differential equations by using suitable transformations. Convergent series solutions of velocity and temperature are obtained. Effects of various dimensionless parameters are observed on the velocity and temperature. Numerical values of skin friction coefficient and Nusselt number are also computed and examined.
