Numerical Simulation of the Abrasive Waterjet Machining: Validation Procedure
Résumé
The increasing use of high-pressure water jets in the industry for machining materials yields numerous studies aiming at the optimization of this technology. Since the experimental study of pure or abrasive water jet cutting is complex to carry out, the numerical simulation of this process stands as an attractive alternative. Such a simulation relies on the coupling of numerical tools devoted on one hand to the description of the high-velocity jet and on the other hand to the deformation of the impacted material. The present paper provides a careful validation for the simulation of an impinging abrasive liquid jet, taking progressively into account the necessary features: impingement, free-surface, particles.
