Two phase numerical simulation of continuous abrasive water jet system based on EDEM

Abstract

To improve continuous supply ability of present pre mixed abrasive water jet (AWJ) system, a new type of continuous AWJ is proposed and its formation mechanism is revealed. Simulation of abrasive entrance and a mixing chamber, pipes, cutting nozzle flow field data using FLUENT software, with area ratio M change, the abrasive cutting nozzle end pressure and entrance into contradiction, the curve of intersection of M=5 is the key point of abrasive jet and material handling division. The solid-liquid coupling simulation method of abrasive particles and water was formed by using edem software.
