射流混药装置结构参数对混药性能影响的模拟分析
Simulation Analysis of Structure Parameters of Jet-mixing Apparatus on Jet-mixing Performance
摘要
Abstract
Aimed at optimizing the structure of jet-mixing apparatus, effect of three main structure parameters: nozzle-tube distance, area ratio and entrainment angle on the mixing performance were investigated based on CFD technique. A mathematical model for jet apparatus was established and validated by actual experimental data. Simulated results and experiment results showed that the established model was reasonable. The results indicated that nozzle-tube distance, area ratio and entrainment angle would not change the tendency of h - q with the increasing of flow ratio. However, both nozzle-tube distance and entrainment angle would not change the tendency oi n - q except for area ratio.关键词
