Abstract :

[en] Measurements of gas hold-up obtained by using pressure transducers and an optical probe are compared with those obtained by an electrical resistance tomography method. The use of a neural network, the input of which is the electrical measurements, can lead to quantitative results for the gas hold-up distribution. An interesting qualitative diagnosis of the sparger functioning is observed from reconstructed images.
