ABSTRACT

A numerical study of steady, laminar, hydromagnetic, boundary-layer flow and heat transfer of a particulate suspension exhibiting finite particle volume fraction over a non-isothermal semi-infinite flat plate with variable properties is performed using a modified dusty-gas model. This modified model allows for particle-phase stresses, magnetic field and heat generation or absorption effects. The development of the displacement thicknesses and the skin-friction coefficients of both phases, as well as the wall particle-phase tangential velocity and the wall heat transfer coefficient are illustrated graphically for various parametric conditions. The results indicate that the presence of a transverse magnetic field causes the displacement thicknesses of both phases to decrease over the whole of the computational domain while the skin-friction coefficients of both phases and the wall heat transfer coefficient increase.
