- 摘要:
- 利用CFD前置处理软件gambit建立扇形喷嘴内部流场的可视化模型,通过fluent软件求解扇形喷嘴高压水射流各节点速度。根据速度场分布云图,分析影响扇形喷嘴高压水射流速度的主要因素。结果表明:扇形喷嘴出口盲端长度和切槽相对偏移量对其内部流场影响较大,圆柱端长度和切槽半角对其内部流场影响较小,切槽半角主要决定射流的散射角。模拟的结果为扇形喷嘴的设计选取提供了一定的理论依据,对实际工程有一定的指导意义。
- Abstract:
- Using the gambit of lead processing software CFD to establish the visual modeling,the speed of fan-shaped nozzle of high pressure water jet was solved by fluent.According to the velocity distribution cloud to analyze the main factors of influence of fan-shaped nozzle high pressure water jet speed.The results showed that export blind side length and relative offset notch of the fan-shaped nozzle influence the internal flow field more,length of cylinder and notch half-width influence the internal flow field little.The simulation results provided theoretical basis for the design of fan-shaped nozzles and had some guiding significance to the actual projects.
