ABSTRACT:
A method and apparatus for producing a coherent stream of high velocity abrasive laden liquid. The method includes allowing the particles to assume the direction and velocity of a high velocity jet of liquid. This method also allows concentration of particles in the center of the flow of liquid to reduce nozzle wear and increase cutting efficiency. The apparatus includes a nozzle having a converging section attached to a straight section that is sufficiently large that the abrasive particles approach the velocity of the fluid jet before exit of the nozzle.
