内容記述 | The smoothed particle hydrodynamics(SPH) method is applied to the numerical simulation of the cutting of a solid body by a highly pressurized water jet. Water is modeled as a viscous çuid with weak compressibility. A solid body is modeled as an elastic material. The water and solid body are discretized into a lot of small volume elements called particles. Those particles are moved in a Lagrangian manner according to the governing equations. To suppress unnatural numerical oscillation in pressure distribution, two stabilizing techniques, such as the artiåcial density diãusion and the density re-initialization method, are employed in addition to the artiåcial viscosity used in the conventional SPH discretization. The combined use of those methods has produced stable computations. Also, a computational model is proposed for a mixture of water and abrasives. Instead of preparing two diãerent kinds of particles for water and abrasives respectively, the mixed çuid of water and abrasives is expressed by single kind of particles. The frictional force caused by an abrasive on a solid surface is modeled by the Coulomb's friction. Encouraging numerical results are obtained. | |||||
