Abstract

The patterns of destruction of an abrasive and the walls of the channel of a nozzle attachment of a waterjet machine during the movement of a multiphase flow modified by surfactants are revealed. The results of modeling the kinematic characteristics of the motion of abrasive particles in a multiphase flow with surfactants, as well as the results of modeling the contact interaction of the abrasive with the walls of the nozzle of a waterjet machine are presented. Conclusions are made about the influence of the geometry of the nozzle channel profile on the destruction of the abrasive and the surface of the jet-forming channel.
