Unsteady Hydromagnetic Flow of Dusty Fluid over a Stretching Cylinder with Variable Viscosity and Thermal Conductivity

This paper deals with the study of unsteady flow of a conducting dusty fluid due to linearly stretching cylinder with variable viscosity and variable thermal conductivity. Present work investigates effects of temperature dependent viscosity and thermal conductivity on the velocity, temperature and species concentration profiles. The partial differential equations governing the boundary value problem are transformed into ordinary differential equations with the help of similarity transformations. Resultant equations are solved numerically using fourth order Runge-Kutta method with shooting technique. The influences of various parameters that characterize the flow on velocity, temperature and species concentration profile have depicted graphically and analyzed for both the fluid and dust phases. Numerical values of skin-friction coefficient, Nusselt number and Sherwood number are tabulated for various parameters.
