Abstract: The magnetohydrodynamic (MHD) flow of third-grade fluid between two permeable disks with heat transfer was investigated. The governing partial differential equations were converted into the ordinary differential equations by using suitable transformations. Transformed equations were solved by using homotopy analysis method (HAM). The expressions for square residual errors were defined and optimal values of convergencecontrol parameters were selected. The dimensionless velocity and temperature fields were examined for various dimensionless parameters. Skin friction coefficient and Nusselt number were tabulated to analyze the effects of dimensionless parameters.
