The influences of angles(45.0°,60.0°,67.5°,75.0°) of dental labyrinth channels drip emitter on hydraulic and anti-clogging performance was studied by the following methods: the CFD numerical simulation of the velocity in the flow field,the PIV observation of the trajectories and velocity of particles in flow path and the samples experiment.The results showed that there is a negative relationship between angle and discharge coefficient together with flow state exponent,in addition with the increasing of the ...
