            摘要:
            噴嘴磨損程度嚴重影響著磨料射流的應用效果,由于噴嘴屬深長孔結構,實驗的方法難以測得磨料運動軌跡及磨損部位。分析了磨料噴嘴磨損機理,采用FLUENT DPM模型對磨料射流噴嘴內部流場進行了數值模擬,通過建立噴嘴內部流場的有限元模型,得到射流參數及磨料參數對磨料噴嘴磨損的影響規律。結果表明,噴嘴磨損程度受射流時間、射流速度、磨料尺寸、磨料濃度等影響較為嚴重。
            Abstract:
            The application effect of the abrasive water jet is influenced greatly by the nozzle wear, but it′s difficult to obtain the wear position of the nozzle through the experiments due to its longhole structure. The wear mechanism of the abrasive nozzle is analyzed, the internal flow field of the abrasive nozzle is simulated based on the DPM model of FLUENT, and the change rules of the nozzle wear influenced by the abrasive parameters and the jet parameters are obtained through building the finite element model of the flow field inside the nozzle. The results show that the nozzle wear is seriously affected by the jet time, jet speed, abrasive size and abrasive concentration.
