Modeling the Movement of a Hydroabrasive Flow with a Surfactant in the Nozzle Channel of a Hydroabrasive Machine

The article presents the results of modeling the movement of a waterjet flow with the addition of a surfactant (SAS) in the channel of a waterjet machine nozzle. Based on the Ansys Fluent computing package, a model of a waterjet flow in the nozzle mixing chamber was developed, an analysis of the turbulence intensity in the mixing chamber of the nozzle was carried out, and the nature of the change in the longitudinal and transverse components of the abrasive velocity along the length of the nozzle was determined, taking into account the presence of a mixing chamber and an SAS additive.
