Effects of Variable Viscosity and Thermal Conductivity on the Flow of Dusty Fluid over a Continuously Moving Plate

Abstract

paper investigates the effects of variable viscosity and thermal conductivity of flow and heat transfer of dusty fluid over a continuously moving plate with suction or injection. The fluid viscosity and thermal conductivity are assumed to be vary as an inverse linear function of temperature. The flow governing equations are transformed into ordinary differential equations and the resulting coupled non-linear boundary value problem is solved numerically using Runge-Kutta shooting method. The results are represented graphically to illustrate influence of the various physical parameters on the velocity and temperature profiles of both fluid and dust phases. Skin friction and Nusselt number are also coupled and presented in tabular form.
