ABSTRACT
Owing to the abundant applications of nanofluids, this study is mainly concerned with the steady, laminar, non-linear MHD flow of nanofluids over a rotating porous disk subjected to prescribed heat flux and suction. Two types of nanofluids such as copper – water nanofluid and silver – water nanofluid are considered. Governing equations are system of nonlinear partial differential equations and they are converted to a system of nonlinear ordinary differential equations by means of similarity transformations. The resulting non-linear ordinary differential equations are solved numerically using Nachtsheim-Swigert iteration shooting technique for satisfaction of asymptotic boundary conditions and employing Runge – Kutta Fehlberg Method. The features of the flow and heat transfer characteristics are analysed and discussed. The radial, tangential and axial velocities are obtained numerically and are represented graphically. Numerical computations for dimensionless temperature, the radial skin friction coefficient and the tangential skin friction coefficient for both the types of nanofluid flows are obtained for various values of physical parameters.
