摘要(Abstract):

采用管道内ISO文丘里喷管测量流量是通风机风管出气性能试验的几种主要方式之一。采用数值计算与实验相结合的方法,对喷管后扩压段的长度选择与流动阻力问题进行了分析研究,并提出了改进建议。
One of the major methods used in fan outlet performance tests is to measure the flow rate using ducted ISO Venturi nozzle.Combining numerical calculations with experimental measurements,the optimum length for the diffuser behind the Venturi nozzle and the flow drag were investigated.Suggestions have been proposed to improve the performance of the test equipment.
