Numerical research on rock breaking performance of water jet based on SPH

The numerical model of rock breaking by water jet was established based on finite element method (FEM) and smoothed particle hydrodynamics (SPH) to research the efficiency of rock breaking by water jet. Firstly, the research on the impact pressure of water jet was conducted under different diameters and velocities. Then, the effect of water jet diameter, jet angle and jet velocity on the efficiency of rock breaking was studied and the reasons...
