This paper examines the fluid dynamical characteristics of the duct flow in a swirlmeter by using the computational fluid dynamics approach. 本文运用计算流体动力学方法研究旋涡进动流量计的流道流体动态特性。
By dividing an extraction zone into a finite number of segments, an analysis for each segment is based upon a direct application of the duct branch with uniting flow. 方法的要点是利用风道支管流量和压损计算的半径验方法，将抽汽流道分成有限个弧段，视每一弧段为一混合流支管，形成计算模型。
