Rapid Stereotype of Cylindrical Drip Emitter Based on Computational Fluid Dynamics and Rapid Prototyping Manufacturing

Abstract:

In the rapid development process of cylindrical drip emitter, the traditional CFD analyzing method was generally carried out based on the planar model of the cylindrical labyrinth channel. However, the result obtained by this method was obviously different with the experimental data. In this paper the cylindrical prototype of the labyrinth channel was proposed and the CFD analysis was carried out based on the hexahedral mesh of the cylindrical labyrinth channel to solve this problem. Then the flow rate and the anti-clogging performance of the emitter were predicted based on the stereo prototype of the labyrinth channel. Consequently, the simulation results were verified and the cylindrical drip emitter was finalized according to its hydraulic performance experiment.
