Abstract
ENERGY INTERNATIONAL PROPOSES TO DEVELOP A COMPREHENSIVE COMPUTER SIMULATION TECHNIQUE TO EVALUATE THE EROSIVE CHARACTERISTICS OF SLURRY JET PUMP SYSTEMS. THE COMPUTER CODE SOLVES A SET OF COUPLED GOVERNING EQUATIONS FOR FLUID MECHANICS, PARTICLE DYNAMICS AND EROSION KINEMATICS. THE CODE WILL BE USED TO VERIFY THE IMPROVED ANTI-EROSION PERFORMANCE OF AN INNOVATIVE SLURRY JET PUMP DEVELOPED BY ENERGY INTERNATIONAL, INC. THE DESIGN IS BASED ON THE CONCEPT OF INTRODUCING THE HIGH-PRESSURE WATER JET FROM THE OUTER ANNULAR REGION OF THE PUMP AND THE HIGH DENSITY SLURRY INTO THE CENTER COVE REGION. IN THIS DESIGN, THE HIGH-PRESSURE WATER JET ACTS AS A WATER JACKET TO PREVENT THE ABRASIVE PARTICLES IN THE SLURRY FROM DIRECTLY STRIKING THE NOZZLE WALL. THIS DESIGN WILL SIGNIFICANTLY REDUCE THE EROSIVE WEAR ON THE PUMP NOZZLE AND THROAT REGIONS, WHICH PRESENTLY LIMITS THE DURABILITY OF STATE-OF-THE-ART PUMPS.
