摘要:
喷嘴磨损程度严重影响着磨料射流的应用效果,由于喷嘴属深长孔结构,实验的方法难以测得磨料运动轨迹及磨损部位。分析了磨料喷嘴磨损机理,采用FLUENT DPM模型对磨料射流喷嘴内部流场进行了数值模拟,通过建立喷嘴内部流场的有限元模型,得到射流参数及磨料参数对磨料喷嘴磨损的影响规律。结果表明,喷嘴磨损程度受射流时间、射流速度、磨料尺寸、磨料浓度等影响较为严重。
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.
