Abstract

Abstract

The shear stress of the slurry flowing in the tube or two-dimensional channel is epressed by the shear stress of Bingham fluid,usually.ie Where τ_B is the yield stress of Bingham fluid and η is the coefficient of rigidity.The author disapproves this point of view The author thinks that the mechanical property of the slurry may be more like that of highly viscous fluid than that of Bingham fluid.Basing on this idea,we adopt another method to treat the mechanical problem.We assume that,for the case of small Reynolds number,the velocity distribution of the slurry is very close to that of Stokes solution,Thus,we map apply the method.of effective viscosity to calculate the resistance force of a sphere moving in the slurry with uniform velocity.
