Abstract

This paper investigates momentum, heat and mass transfer characteristics of a hydromagnetic Newtonian dusty fluid flow due to a rotating disk with radiation and viscous dissipation. The main objective of this paper is to study effects of temperature dependent viscosity and thermal conductivity on flow, temperature and species concentration. Radiation and viscous dissipation effects are also taken into account. Saffman model for dusty fluid is considered for the problem. The partial differential equations governing the flow are converted into ordinary differential equations employing similarity transformations. The resulting highly nonlinear coupled ordinary differential equations are solved numerically using shooting technique with fourth order Runge-Kutta integration scheme. The influence of variable fluid viscosity, variable thermal conductivity, fluid particle interaction, magnetic interaction and radiation parameters as well as Eckert number are presented graphically and discussed for velocity, temperature and species concentration profiles. Numerical values of the wall shear stress, rate of heat transfer (in terms of Nusselt number) and rate of mass transfer (in terms of Sherwood number) are obtained, analyzed and presented in tabular form.
