摘　　要：涡街发生体是涡街流量计的关键部件之一,其流体力学外形决定了涡街流量计的量程、精度。设计了一种新型的涡街发生体,并通过CFD软件FLUENT对新型涡街发生体和目前常用的涡街发生体进行数值仿真、理论分析和比较。结果表明:在实际应用中,新型涡街发生体的流体力学性能优于其他涡街发生体,适合高、低流速下产生强度大且稳定的涡街。Vortex generator is an important component of vortex flowmeter. The shape of CFD decides vortex flowmeter＇ s range and accuracy. A novel vortex generator is disigned, its numerical value is simulated and the theory is analysed by FLUENT, and the other common generators are compared with it. As a result, through practical application, the advanced vortex generator has a better performance than others, it is able to make powerful and steady vortexes in low or high Renault value.
