Abstract

The process of sand-wall collision was performed to analyze the relationship between the collision and clogging of labyrinth channel emitter. First, the effect of R_c on pass rate of sand was analyzed using the CFD method. It was found that R_c has a great impact on the anti-clogging characteristics of labyrinth emitter and should be determined through experiments. In order to provide the experimental basis for the setting of sand R_c in numerical simulation, experiments of PTV were carried out for the determination of R_c under various pressure and different structure of labyrinth channel emitter, so that the anti-blocking performance can be more accurately evaluated.
