Abstract
In order to reduce the complexity of pressure-compensating emitters (PCE), a new integral PCE was designed. And a rapid experimental method was proposed based on RP&M. Utilizing orthogonal experiment, the integral emitters were fabricated to perform rapid experiment based on RP&M by taking the structural parameters of pressure-compensating area as factors. It is found that the unit channel number and the sheared depth have a significant effect on emitter's compensating performance, and the dimension of labyrinth channel on the emitter body is the most important factor for the flow of the PCE. The regression relationship of structural parameters-flow rate and flow behavior index were established and verified through experiment. Then, by analyzing the flow field distribution using the numerical simulation of two phase flow of solid-liquid, the anti-clogging mechanics of pressure-compensating emitter has been disclosed.
