In this paper, we have studied the transport of heat and mass in viscous fluid flow over a rotating disk. Six PDE's control the fluid motion along with the diffusion of these quantities over such a disk. The system of PDEs is transformed into a set of ODE's, which is solved numerically in MATLAB.

This paper presents the double-diffusive convection in the flow of viscous fluid over a heated, rotating, porous and moving disk. All the field quantities, defined at the surface of such disk, are nonuniform and nonlinear. The boundary conditions of the simulated problem are nonhomogeneous and variable.

Viscous flow is maintained over a porous and rotating disk. The porous disk is stretched (shrunk) with the non-uniform velocity in the radial direction. Note that the viscous fluid is injected (blown) normally with non-uniform velocity. The study is undertaken by considering the combined and individual effects of injection (suction), stretching (shrinking) and rotation. The kinematics properties associated with the disk are depending upon the radial coordinate.
