Furlan, Ph.D., Hydraulic Design Engineer, GIW Industries, Inc., Groveton, GA “Pumping high yield stress non-Newtonian clays with centrifugal slurry pumps” Abstract: Due to increasing demand for water resources, mining technologies which reduce consumption are becoming more prevalent. One such technology is the use of high solids concentration paste, or thickened slurry pumping, which allows mines to operate tailings systems with less water. Often such slurries exhibit non-Newtonian behavior, which can result in significant effects on pump performance. In order to investigate such effects, a 100-600 Pa yield stress clay slurry was pumped using a centrifugal pump at the GIW hydraulic lab. In order to remove entrained air from the slurry, a modified tank arrangement was employed. Derates were relatively modest and showed a stronger dependence on pump rotary speed than that predicted by standard derating techniques. The backwards sloping (unstable) head curve seen in previous studies was not observed while employing the modified tank arrangement. It is possible that observed difficulties in pumping slurries with similar rheologies in previous studies utilizing closed loops may have been the result of pump airlock. About the Speaker: John Furlan is a hydraulic design engineer at GIW Industries in Grovetown, GA, USA. He graduated with a Ph.D. in mechanical engineering from Case Western Reserve University in 2011. He is responsible for hydraulic design, wear and performance prediction of centrifugal slurry pumps. John performs research in the areas of solid particle erosion and wear, solidliquid, and gas-liquid flows. _____________________________________________________________________________________________ Location: The Presidential Dining Room is on the upper floor of the Maxwell Student Union located at corner of N.
