Abstract :
Electromagnetic Tomography technology has bright future in the two-phase flow measurement, and the study of the image reconstruction algorithm is important to improve the measurement accuracy. A new kind of algorithm based on Modified Newton-Raphson method was proposed and applied to the EMT image reconstruction for solid-gas two-phase flow measurement. The simulated reconstruction results of the new algorithm together with that of the direct algorithm (LBP) showed that the new algorithm is suitable for industrial online two-phase flow measurement for its advantages in aspects of computation cost and reconstruction quality.
