A CFD Modelling Of Abrasive Waterjet Nozzle Wear Profile
The profile of the Abrasive Waterjet (AWJ) Machine nozzle wear was simulated using Computational Fluid Dynamics based software. Due to the impact velocity of water and the entrained abrasive particles within the nozzle, erosion of nozzle is inevitable and it is the most critical part in ensuring kerf quality of the AWJ machine. The Discrete Phase Method (DPM) was used to determine the erosion rate. The simulated results indicate wavy pattern of wear profile which correlates well with worn out nozzles.
