Abstract

Based on electrical capacitance tomography technique, a new method for the void fraction measurement of two-phase flow is proposed. A void function measurement system is established, A mathematical model of image reconstruction of electrical capacitance tomography is developed. To obtain the quantitative information of two-phase flow, a new image reconstruction algorithm is presented. The experimental results show that the accuracy of void fraction measurement is satisfactory. The proposed method is suitable for the void fraction measurement of many kinds of two-phase flow
