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.
