摘要：

In this paper we study the effects of variable viscosity and thermal conductivity on the heat transfer and flow of a slag-type non-Newtonian fluid between two horizontal flat plates. We solve the governing equations in their non-dimensional forms and perform a parametric study to see the effects of various dimensionless numbers on the velocity, volume fraction and temperature profiles. The different cases of shear- thinning and thickening, and the effect of the exponent in the Reynolds viscosity model, for the temperature variation in viscosity, are also considered.
