Application of PLSR to the Voidage Measurement of Gas-oil Two-phase Flow

摘要：

Based on ECT technique and Partial Least Squares Regression (PLSR), a new voidage measurement method for gas-oil two-phase flow was proposed. PLSR was utilized to develop the voidage measurement models for given flow patterns. In practical voidage measurement process, according to the flow pattern identification result, a related PLSR based model was selected to calculate the measurement voidage. Experimental results show that the proposed method is effective and the accuracy of the voidage measurement is satisfactory. The maximum measurement error is less than 5 ?. Research results also verify the good real-time performance of the proposed voidage measurement method. Because it implements the voidage measurement without the time-consuming image reconstruction process, the total voidage measurement time is less than 0.1s.
