Numerical Simulation and Experimental Study of Internal Flow Field of the Jet Pesticide Mixer

采用实验验证和数值模拟相结合的方法,利用Pro/e建模,Gambit网格划分,FLUENT三维流场模拟对射流混药装置内部流场进行计算分析,针对射流混药装置工作流体和吸入流体密度不同时,研究其对射流混药装置性能的影响。模拟计算中采用k-ε湍流模型,使用SIMPLEC算法;实验流体采用不同密度的NaCl溶液。模拟结果可以为射流混药装置的内部流场的性能研究提供依据。

The paper combines numerical simulation with experimental study,using the method of pro/e modeling,meshing in Gambit soft,making three-dimensional flow field simulation in FLUENT soft.According working fluid and inhaled fluid density is not the same in the jet pesticide mixer,study the performance influence of the jet pesticide mixer.Simulation adopts K-εturbulence model,using SIMPLEC algorithms.Fluid experiment using the different density of NaCl solution.Simulation results can be used for the future study of jet pesticide mixer.
