摘要
根据已知圆管紊流流速分布的近似模地,研究了使用管道轴线处的最大流速测量流量的方法。通过实验验证了这种方法的正确性和可行性,并得到了相关的实验公式。该方法具有简单、准确、节能等特点,有较好的应用前景。
According to the approximation of the velocity profile of turbulent flow in cylindrical pipes, flow rate measurement based upon the maximum velocity of circular cross-section is proposed. A correlation based on measurements is given. It is shown that the method is simple, accurate, economic and promising on flow rate measurement.
