本文介绍了应用电容相关测量系统对气／固两相流团相速度的测量。应用该系统获得了双峰互相关图形。研究了双峰互相关函数与气／固两相流流动特性的关系，并给出了相应的实验结果。分析了江峰现象及固相的脉动输送对测量固相速度所产生的误差。
This article describes the measurement of the phase velocity of a gas / solid two-phase flow using a capacitance-related measurement system. The system was used to obtain the bimodal cross-correlation graph. The relationship between the bimodal cross correlation function and the gas / solid flow characteristics was studied, and the corresponding experimental results were given. The error of Jiang Feng phenomenon and the pulsation of solid phase on the measurement of solid velocity was analyzed.
