Observations of Abrasive Water Suspension Jets by Instantaneous Photographs. Influence of Abrasive Particle Type on Jet Structure.

Abstract

Experimental studies are carried out to clarify the effects of abrasive particle type on the structures of the abrasive water suspension jets. Observations of the jets are conducted at the injection pressure of 12 MPa with seven types of abrasives, two types of steel bead, two types of aluminum oxide, two types of glass bead, and a type of plastic shot. The experiments show that the jet structures are affected greatly by the type and the concentration of the abrasive. By using smaller abrasive particles, the jet becomes compact. However, larger abrasive particles tend to promote the jet breakup. These tendencies are noticeable in the case of the abrasive with high density.
