DISPERSION OF MATTER IN FLOW OF A BINGHAM PLASTIC IN A TUBE

Abstract

The paper is concerned with the dispersion of a solute in a Bingham plastic fluid flowing in a pipe or a parallel plate channel. For pipe flow, the dispersion coefficient K ₂ first increases with ξ₀ (the dimensionless radius of the plug flow region), reaches a maximum and then decreases. But in a channel flow, K ₂ decreases monotonically with increasing ξ₀. Further K ₂ for channel flow is found to be larger than that for pipe flow for all values of ξ₀ except 0.8≤ξ₀≤1.
