Selection of the Nozzle for Metal Surface Cleaning Using Cavitating Pulsing Fluid Flow
The aim of the research was to define an appropriate design of the nozzle which could be used to cavitate microbubbles and direct the cavitating water flow on the cleaning metal surface. Three different nozzles were evaluated. SolidWorks 2011 Flow Simulation software was used for calculations. Volume of vacuum bubbles in the flowing part of the nozzle was established. The water pressure at the inlet was varied from 4 to 10 MPa. Calculations show that in all nozzle structures amount of bubbles change slightly while pressure is varied from 4 to 10 MPa, so the optimal pressure of the water flow can be considered as 4 MPa.
