Hydraulic Characteristics of Pressure Compensating Emitters Based on Fluid-structure Interaction
摘要
Abstract
The hydraulic characteristics research of the pressure compensating emitters which have the advantages of flow uniformly, anti-clogging strongly has mostly by the experiment, but less on the flow field. Considering the effect of fluid-structural interaction, Computational Fluid Dynamics (CFD) modeling of flow of the pressure compensating emitters is studied in this paper. Pressure and flux characteristic of pressure compensating emitter, the flow field distribution and elastic diaphragm deformation were obtained by simulation. And the results indicate that the study on the pressure compensating emitters hydraulic characteristics using the CFD simulation method based on fluid-structure interaction is reliable. Therefore, it provides a new method for development of new pressure compensating emitters.关键词
