小管径超声波流量计的仿真与设计
Simulation and Design of the Small Pipe Ultrasonic Flowmeter
摘要
Abstract
In order to solve the problem of small pipe measurement of transit-time ultrasonic flowmeter, the inner acoustic reflection device and tapered pipe were designed. The flow correct coefficient K and its RMS error were adopted as the evaluation standard. The shape, size and distance of the reflectors and the size of tapered pipe were studied with FLUENT software. Then the optimal pipe model was designed. The coefficients of the model at different flow points were also calculated. The simulation results showed that the flow pipe model is stable and can improve the accuracy of the small pipe measurement.关键词
