摘要

A continuum model for two-phase (fluid/particle) flow induced by natural convection is developed and applied to the problem of steady natural convection hydromagnetic flow of a particulate suspension through an infinitely long channel in the presence of heat generation or absorption effects. The walls of the channel are maintained at constant but different temperatures. The developed model accounts for particle-phase viscous stresses. Boundary conditions borrowed from rarefied gas dynamics are employed for the particle-phase wall conditions. Various closed-form solutions for different special cases are obtained. A parametric study of some of the physical parameters involved in the problem are performed to illustrate the influence of these parameters on the flow and heat transfer aspects of the problem.
