TWO-PHASE FLOW MEASUREMENT BY DUAL-PLANE ERT SYSTEM WITH DRIFT-FLUX MODEL AND CROSS CORRELATION THECHNIQUE
The flow rate measurement in two-phase flow is hard to achieve, because the phase interaction is complex, especially in large diameter pipes. According to one-dimensional continuity equation and kinematic theory, it is assumed that, the correlation velocity is equal to the naturally occurred kinematic propagation speed of two-phase flow. The actual speed of disperse phase can be predicted by the correlation velocity with drift-flux model in two-phase flow. In this paper,the experiments of gas-liquid two-phase slug flow in a vertical large diameter pipe are brought out. Based on the experiments and drift-flux model, the relation of correlation velocity to kinematic propagation is investigated. A new method of cross correlation by dual-plane ERT system is introduced. It is approved to be competent for two-phase flow measurement under this kind of condition.
