Abstract

In method and apparatus for producing a coherent stream of high velocity abrasive laden liquid, the method includes allowing particles of abrasive to assume the direction and velocity of a high velocity jet (22) of liquid. The method allows concentration of particles in the centre of the flow of liquid to reduce nozzle wear and increase cutting efficiency. The apparatus includes a nozzle (21) having a converging section (26, 27) attached to a straight section (28) that is sufficiently large that the abrasive particles approach the velocity of the fluid jet before leaving the exit (29) of the nozzle.
