Abstract
The abrasive water jet consists of water and solid tiny particles. The cutting by abrasive water jet mostly progresses by particles. Therefore it is necessary that the particle distributions should be clear to know the cutting ability. This paper describes on the experimental study on the particle distributions in abrasive water jet. The measurements of distributions are carried out by gathering the water and particles in the box with a hole so that a part of the jet is able to go through. As the result, both the water and the particle mass distributions change by the condition of the jet and the nozzle shapes. Moreover, the 2nd peak appears in the particle mass distribution.
