摘要
本文分析了影响文丘管测量结构几个主要的结构参数:收缩比β、扩张角θ2、收缩角θ1,具体研究了单文丘利管及双文丘利管的优化设计,并进行了大量的冷态模化实验,得出了双文丘利管的最优结构参数,以及流量、流速与压差的关系式。
Abstract An analysis was made on the key parameters affecting the Venturi performance,such as β_contraction rate,θ 1-contration angle,θ 2-expansion angle.Based on design optimization and some cold model experiments,optimum structure parameters for the double ones and the relationship between flow rate (velocity) and pressure difference were obtained.
