Structural Design of Nozzle Based on Hybrid Laser/Water-jet Scribing Technology

摘要

In order to research the effect of nozzle geometric parameters on the jet flow performance in processing a thin and sensitive material. A design of two nozzles with different structure has been proposed for hybrid laser/water-jet scribing technology. In this paper, computational fluid dynamics (CFD) method was used to simulate and analyze the gas-water two phase flows of water jets. Compared with cylindrical nozzle, the results show that conical nozzle obtains a greater pressure field and more stabilized velocity field. As a result, by comparing the optimization can get the optimum nozzle structure parameters.
