Powder Technol 30:747 768.], the b-r two-fluid model is capable of accurately reproducing the main features of turbulent, fully-suspended slurry flows in horizontal pipes provided that suitable values of the two parameters b and r are chosen. At present, the case-specific nature of b and r and their lack of a clear physical meaning are the main obstacles that must be overcome to give the b-r two-fluid model value not only as interpretative tool, but also as a predictive one. An important preliminary step to achieve this goal is to disclose the mathematical essence of the b-r two-fluid model, namely, to interpret the fluid-dynamic solution on the grounds of the structure of the differential and discretized equations. Such a methodological approach is applied here to the benchmark case of turbulent slurry flow between two infinite, horizontal, parallel plates, focusing, in particular, on the influence of the bulkmean velocity of the slurry and the volumetric concentration of the solids in the flow. The study provides not only deeper insight into the b-r model, but also indicates important implications for alternative two-fluid models.
