Numerical modeling of abrasive waterjet to optimize rock cutting parameters
Abstract This research was conducted to determine the optimal parameters affecting the quality and efficiency of rock cutting by high-pressure Abrasive Water Jets (AWJs). The process was simulated using the combined Finite Element Method-Smoothed Particle Hydrodynamics (FEM-SPH) in LS-DYNA software. In order to validate the two-phase state of numerical model, several experimental tests were performed on Sandstone and Marble rock samples. The effect of parameters such as jet flow velocity, dwell time, abrasive volumetric concentration (feed rate), and diameter of
