摘要:      由插入式静电传感器的点电荷数学模型得到了固相流速的空间滤波测量原理,同时在实时测量流速的过程中采用了“3dB”原则获取信号的截止频率。通过实验验证了插入式静电传感器空间滤波原理的可行性,建立了一套气/固两相流流体速度模拟实验装置,该装置可以在1~25m/s速度范围内完成固相速度空间滤波速度测量。并采用环状电极互相关速度标定了此空间滤波法测量得到的速度。实验结果表明:得到的插入式电极空间滤波速度测量模型可以在宽范围内实现固相速度测量。

Abstract: The spatial filter measurement principle of flow velocity was obtained by point charge mathematical model of the electrostatic sensor inserted, and signal cut-off frequency was acquired with “3dB” principle during real-time measuring flow velocity. Experiments prove that the spatial filter measurement velocity principle of inducement probe is feasible, and a set of experiment equipment was made-up to measure the solid phase velocity of gas-solid two phase flow, with which the spatial filter velocity may be measured in range of 25 m/s. The measured spatial filter velocity was calibrated by the correlation velocity of ring electrostatic sensor. It may be obtained from the measurement results that the deduced velocity measurement model of spatial filter method may complete measuring solid phase velocity in wider range.
