Numerical Simulation on Hydraulic Cavitation of Venturi Injector
摘要
Abstract
A bstr act:The Venturi injector is widely used in the Water and fertilizer synchronization irrigation.Its structural parame-ters have significant effect on irrigation effect.However, there is little research on its structure design and parameter opti-mization,and there is no uniform standard.Hydrodynamic cavitation is a complex fluid dynamic phenomenon occurring at the throat of the venturi injector when the pressure reaches a critical value.It is necessary to consider the internal cavitati-on of venturi injector for its structural design and parameter optimization.This paper presents a numerical simulation mod-el for internal flow of venturi injector which considers the effect of hydrodynamic cavitation.The numerical simulation re-sults are in agreement with the experimental results, which can provide technical support for the simulation calculation, structural design and optimization of Venturi injector.关键词
