Description

Water jets issuing from a fan jet nozzle (fan jets) are used in radiological decontamination, coating removal, and cleaning. However, the flow characteristics of fan jet have not been clarified sufficiently. An experimental study is conducted to clarify the flow structures and the velocity fields of fan jet and abrasive suspension fan jet issuing from a fan jet nozzle. The velocity fields of the fan jets and the abrasive fan jets are calculated using PIV (Particle image velocimetry). It is found that the time average velocity field of the abrasive fen jet is lower than that of the fan jet.
