Engineering Development of the Novel Slurry Jet Pump

摘要

The objective of the project was to develop a slurry jet pump design that would extend in-line service through erosion control by fluid dynamic means. Experimental tests were performed to characterize the performance and erosion of jet pump under a variety of flow and pump geometry conditions. A comprehensive numerical slurry jet pump model simulating the complex slurry transport, developed during Phase I, was further refined during Phase II to optimize jet pump design with maximum pumping efficiency and minimum erosion in specific applications. Results indicate that pumping efficiency is primarily dependent upon the primary and slurry flow areas at the pump throat and the corresponding volumetric flow rates. The slurry to primary area ratio is an optimization parameter to maximize the slurry pumping at a given primary flow condition.
