Design of Nozzle in Water Jet for Cutting Waste Steel and its Experiments

A nozzle is the key component in the water jet cutting system.The effects of some parameters on the axial jet velocity are studied,such as the first step diameter、the second step diameter、the mixture cavity diameter、the throat pipe distance、the system pressure 、the abrasive diameter,which are fundamental for a nozzle optimal design The results can guide for the design of high pressure water jet cutting machine.
