- Abstract:
- Abstract : This paper presents an application of ultrasonic tomography for detecting the multiphase flow through reconstruction of the cross sectional image of flow. The image is based on the distribution of ultrasonic wave velocity in the flowing medium and reconstructed from measuring the propagation time of ultrasonic wave on the transducers placed around the pipe. We measure the propagation time of ultrasonic wave traveled crossing the pipe from a transmitter to a receiver and we calculate the average velocity as the projection data for the reconstruction process. By using the filtered backprojection algorithm, the image of multiphase flow can be reconstructed.
To validate the proposed method, we performed a computer simulation. We considered that the simulated flow regimes are the combination of water, oil and gas. The flow regimes are simulated in the mathematical model of ultrasonic wave velocity distribution inside the pipe. The simulation results showed that the images produced by the proposed method agree qualitatively with the simulated flow regimes. - Keywords:
