【摘要】 提出一种基于滑速比的计算模型,用于高含气率工况下气相流量的计算和预测,并采用伽马射线探测器加文丘里管的测量技术方案进行了实验验证。实验结果表明,对体积含气率在92%~100%的工况,新模型的高含气率气-液两相流流量的预测结果与真实气相流量相对误差保持在?10%以内。更多还原

【Abstract】 In this paper,a slip ratio based calculation model was developed to predict the gas mass flow rate under high gas volume fraction conditions,which was verified against an experimental investigation with a Venturi meter and a gamma ray attenuation system.Experiments showed that the new model could accurately predict the gas mass flow rate with the relative errors less than ?10% when the gas volume fraction ranging from 92% to 100%.更多还原
