Abstract

A method based on Electrical Capacitance Tomography (ECT) and an improved Least Squares Support Vector Machine (LS-SVM) is proposed for VOID FRACTION measurement of oil-gas TWO-PHASE FLOW. In the modeling stage, to solve the two problems in LS-SVM, pruning skills are employed to make LS-SVM sparse and robust; then the Real-Coded Genetic Algorithm is introduced to solve the difficult problem of parameters selection in LS-SVM then. In the measurement process, the flow pattern of oil-gas TWO-PHASE FLOW is identified by using fast back-projection image reconstruction and a fuzzy pattern recognition technique and the VOID FRACTION is computed using the VOID FRACTION model corresponding to the identified flow pattern. Experimental results demonstrate that both the improvement of LS-SVM and the parameter optimization are effective. The results also show that the real-time performance of the proposed VOID FRACTION measurement method is good, and the measurement precision can satisfy the application requirement.
