摘要 电容层析成像在气力输送过程中具有十分重要的应用地位 ,可进行固相浓度分布测量 ,流型判断。利用双层电容层析成像传感器不仅可以进行浓度测量还可以进行相关测速。基于这种思想 ,设计了一种双层电容传感器 ,与电容测量系统结合 ,用于气力输送过程固相浓度和速度的测量。 Electrical capacitance tomography(ECT) has an importance role in gas/solid flow measurement.It can be used to calculate the solid fraction and identify the flow pattern in multiphase flow such as gas-solid flow.Dual-plane ECT can be used for flow velocity measurement.Based on this idea,a dual-plane ECT system was developed using to measure the solid flow velocity with the cross-correlation method.
