Experimental and numerical studies of the work process in pneumatic abrasive installations

The material presents methods for studying various nozzle configurations.The validation of the numerical studies was performed by comparison of the results of the jet reaction force A with a variety of absolute pressure values at the nozzle inlet, because the jet reaction force value affects the time and efficiency of the material processing. The higher the force A value, the higher is the air-abrasive mixture speed value and the more effective the nozzle is.
