Emitter with tooth-labyrinth paths was main research subject.The distribution law of sand content and hydraulic performance of emitter were analyzed by CFD(computational fluid dynamics)two-phase simulation technology firstly.The optimal design method of labyrinth paths was proposed that the lesser isoline of sand content was regarded as the borderline of labyrinth paths.According to the results of two-phase CFD simulation on the optimal structure,the sand content of labyrinth paths by optimized was more uni...
