AI Technical Summary
Traditional flow measurement methods cannot meet the complex working conditions and high precision requirements of large-diameter wind tunnels. They suffer from problems such as insufficient accuracy, poor adaptability to working conditions, difficulty in calibration, high maintenance costs, and high energy consumption, and cannot meet the measurement needs of large-diameter wind tunnels.
By obtaining the flow field parameters of the target pipe section, calculating the flow field distortion coefficient, correcting the average differential pressure, and combining the initial operating parameters for numerical conversion and error correction, the gas flow rate measurement result is obtained.
It improves the accuracy of gas flow measurement in large-diameter wind tunnels, is suitable for high-precision measurement under complex working conditions, reduces maintenance costs, and optimizes energy consumption.
