摘要
对某一特定型号的迷宫式调节阀,用solid works建立其内部流场模型。通过前处理软件Gambit划分并生成计算网格,应用CFX(流体力学数值计算模块之一)方法对调节阀内部流体流动特性进行仿真,得到该阀内流场流动特性的三维可视化结果。根据仿真结果绘出调节阀的流量特性曲线,与试验测定的数据进行比较分析。结果表明模拟值与试验值较好的吻合,为后续研究新的阀门、阀门故障诊断以及阀门流场优化等研究提供很重要的依据和参考。
Focused on a particular type of labyrinth regulating valve, with its three-dimensional solid model solid works established its internal flow model as the research object. Divided and generate computational grid by pre- processing software Gambit. Application method CFX internal fluid flow control valve characteristics simulation, the valve flow characteristics of flow field visualization results. According to the simulation results analysis labyrinth valve flow characteristics of the internal flow field obtained under different openings in the spool of the valve flow characteristic curve and the same ideal opening under pressure and quality of the relationship between the flow curves for the new follow-up study valves, It was shown by the comparison of the simulation data to those of experimental measurement that the former was well consistent with the latter, providing a basis for further optimization and design of the control valves.
