摘要
针对孔板流量计流场分布问题,应用计算流体动力学软件,对流体流经标准孔板前后的流动状态进行仿真研究,得到了流体流经标准孔板前后的压力流线、速度流线以及压力的分布曲线.通过对流线和曲线的分析,得出了流体流经孔板流量计的一些特点.该研究结果对于应用计算流体动力学软件测量流体的流量提供了方向,同时,对标准孔板流量计的开发也具有一定的指导及借鉴意义.
Aiming at the flow field distribution problem in the orifice flowmeter, the flow behavior of fluid across the standard orifice was simulated using the computational fluid dynamics software. The pressure and velocity streamline in the standard orifice flowmeter as well as the pressure distribution curve of the standard orifice in the centefline were obtained. The flow characteristics of fluid across the standard orifice flowmeter were determined through analyzing the streamline and pressure distribution curve. The results are useful to the flow measurement of fluid by using the computational fluid dynamics software, and have the instructive and available significance for the development of standard orifice flowmeter.
