Structural Design and Flow Field Characteristics of a Two-Stage Nozzle for Pre Mixed Abrasive Water Het
As an energy conversion component in a water jet system,the stability of the nozzle directly determines the performance of the jet,which is crucial in premixed abrasive water jets.The failure mode of the nozzle is mainly caused by wear and tear.This study designed a two-stage contraction nozzle structure consisting of a conical surface and a curved surface by studying the wear mechanism of traditional nozzles.Based on the orthogonal method,analyze and study the factors that affect the performance of the nozzle,so as to optimize the structure with less wear when combining flow field performance.The results show that increasing the contraction section of the curved surface can effectively reduce wear,and the maximum erosion wear is reduced by 96.34％.
