It has been shown that the premixed abrasive water jet system has a greater capacity for drilling and cutting than the conventional abrasive water jet system. In the present investigation, the motion of spherical particles in a premixed abrasive water jet nozzle is investigated theoretically. The flow in the nozzle is treated as one-dimensional flow. Convergent nozzles with and without a cylindrical focusing section are studied. The numerical results show that the particle velocity at the outlet of the nozzle has a tendency to increase in proportion to the square root of the injection pressure. The outlet particle velocity decreases with increasing diameter and specific gravity of the particles. The optimum length of the focusing section increases with increasing diameter and specific gravity of the particles.
