A simple analytical model for predicting the characteristics of low aspect ratio, symmetrical, radial vortex amplifiers, operating with Newtonian fluids and having turbulent flow within the chamber has been modified to treat the corresponding non-Newtonian case. Comparison of the predicted results with the experimental results of this study show that the model attains some measure of success, over a limited range of power law index, but fails to properly represent the shape of the characteristic curve. In addition, the influence of the degree of pseudoplasticity of the operating fluid on vortex amplifier characteristics has been experimentally investigated. The experimental conditions included both symmetrical and asymmetrical triodes, conical and cylindrical receivers, discharge directly to atmosphere and also from a submerged exit. Five concentrations of Separan AP-30 were used, covering a wide range of pseudoplasticity for this solution. The effects of these combinations have been established.
