摘要
新型插入式节流装置用于实际流体流量的测量。在对实际流体动量平衡方程相似转换的基础上,得出过程相似函数,通过风洞实验和数据分析,确定了相似函数的待定系数,用于实际流体流量的测量和计算以及节流装置的设计改进。
New plug-in throttling device was applied in flow measurement of real fluid.The process similarity function was summarized based on similarity transformation of actual flow momentum balance equation.According to wind tunnel experiments and data analysis,the undetermined coefficients of the similarity function were determined.The result could be used in actual flow measurement calculation and throttle device design improvement.
