双锥流量计的气水两相流流量测量研究

摘要

采用一种新型双锥流量计,对气水两相流流量的测量进行试验研究.通过试验的方法,在水流量标准装置上对双锥流量计的流出系数进行了标定.利用双锥流量计的差压信号,采用分相流模型、Lin模型和Murdock模型对气水两相流的总流量测量进行了初步的研究.结果表明,在一定的测量范围内,采用Murdock模型可以获得较好的测量结果.%By adopting the new type of dual-cone flowmeter, the measurement for two-phase of gas/liquid flow is tested and experimented. Through experimental method, on flow standard device for water, the flow-out coefficient of dual-cone flowmeter is calibrated. By using the d/p signal of dual-cone flowmeter, with phase flow model, Lin model and Murdock model, the total flow of the gas/liquid two-phase flow is researched preliminary. The result indicates that in certain measurement range, with Murdock model, better measurement result can be obtained.
