Abstract
Stereolithography technology is adopted to fabricate the integral structure of emitters and outer pipes, and the experiments of emitter hydraulic performance are carried out with orthogonal design method, where the key parameters of triangle channel are distinguished. The results obtained from range analysis and variance analysis show that the channel turning angle is the most important factor affecting the flow index, and the flow rate is seriously influenced by the number of channel units, which facilitates settling the problem of increscent flow rate due to the structural optimization. A model is established between structural parameters and hydrodynamic behaviors according to the linear multivariable regression method, which is verified being able to forecast the relationship between the flow rate and pressure loss for the emitters with triangle labyrinth channels.
