Searching lately trough the AWJC web i found this amazing research from the technical research center in Chania - Crete - Greece. A member of the research team Mrs. Phys. Maniadaki Kyriaki (MSc) has uploaded the following interesting animation.
Simulation Details:
Compared with traditional and most non-traditional machining technologies, AWJ cutting technology has a number of distinct advantages, such as no thermal distortion, high flexibility, high machining versatility and good surface quality, easy integration with mechanical manipulators, low machining force and minimal burrs. The utilization of the AWJ cutting/drilling and in particular its application into hard-to-cut materials is growing. Consequently, the waterjet and abrasive waterjet technology has been a subject of research for a number of years and the main stream of research has been directed towards the understanding of the complex material removal mechanisms and the optimization of the process parameters (fluid dynamics and technological) for various applications
In the current study, work was undertaken to accurately simulate the pure water jet flow of the process. The flow has been divided into three regions, inside the waterjet nozzle, the waterjet flow into the air and the waterjet impact on a non-moving target material as well as the impact on a moving target. What distinguishes this project from previous work is that the overall waterjet process is simulated including the nozzle waterflow simulation. At this stage of research the waterjet velocity profile that is created at the exit of the nozzle is computed and its form is known vs. time. The main objective is to investigate and analyze in detail the material behavior under waterjet impingement.
