The Flow-Field Simulation and Experimental Research of the New-Type High-Pressure Water Jet Nozzle in Descaling

It designs a new type high-pressure water jet nozzle in descaling after considering the disadvantages of fan nozzle. This type nozzle depends on the hitting power and the vapor expand bursting force to accomplish the descaling technics. The numerical simulation calculation and the experimental research reveals that water jets are influenced by the adjacent water jet in this type nozzle and the outer water jets spreads faster than the inner water jets. The jet hitting power becomes weak along with the water-jet distance becoming long. When in the same water-jet distance,the jet hitting power of the outer water jet is weaker than the inner water jet. At last,this type nozzle is applied in thermal descaling production line. It is confirmed that this type nozzle is adequate for industry,but it has to make an optimization design.
