要約

Two approaches to evaluate pressure drop for non-Newtonian slurries at high concentrations have been evaluated by the comparison with the data for fly ash slurries. The first approach involves the pilot plant test data and the second approach involves the choice of semi-empirical pressure drop correlations based on rheometric data. Finally both approaches are compared in quantitative terms. The variation in the results is within the permissible limits. Hence the second approach can be adopted by the slurry pipeline designers instead of resorting to the extensive pilot plant tests which is tedious, time consuming, uneconomical and complex in nature.
