摘要：

为了研究工程实际中多孔板和楔形节流装置内部流场的流动特性，并为流出系数的获取提供新的途径，采用计算流体动力学方法对多孔孔板节流装置和楔形节流装置的内部流场进行了数值仿真研究，并将数值模拟得到的流出系数与流量标定实验结果进行对比，来验证数值模拟结果的合理性与精确性．实验结果表明，流出系数的流量标定结果与数值模拟值之差小于4％，对多孔孔板和楔形节流装置工程设计提供了参考．

关键词: 多孔孔板节流装置, 楔形节流装置, 计算流体动力学仿真, 流出系数

Abstract:

To study the flow characteristics of multi-hole orifice and wedge throttle devices in engineering application and provide a new approach to the estimation of the discharge coefficient, the computational fluid dynamics (CFD) method is used to numerically simulate the internal flow field of multi-hole orifice throttle devices and wedge throttle devices,by comparing the discharge coefficient achieved from numerical simulation and the experimental results of flow calibration to verify the rationality and accuracy of the numerical simulation results. It is indicated that,compared to the experimental measurement of the flow,the discharge coefficient obtained from the numerical simulation is less than 4％, and is the reference for engineering design.

Key words: multi-hole orifice throttle devices, wedge throttle devices, computational fluid dynamics simulation, discharge coefficient
