| Abstract | Experimental results on the flooding capacity of randomly dumped packed beds were collected from the literature to generate a working database. The reported measurements were first used to review the accuracy of existing predictive tools in that field. A total of 14 correlations were extracted from the literature and cross-examined with the database. Many limitations regarding the level of accuracy and generalization came to light with this investigation. Artificial neural network modeling was then proposed to improve the broadness and accuracy in predicting the flooding capacity, which is an important design parameter for packed towers. A combination of six dimensionless groups, namely, the Lockhart−Martinelli parameter (χ); the liquid Reynolds (ReL), Galileo (GaL) and Stokes (StL) numbers; the packing sphericity (φ); and one bed number (SB) outlining the tower dimensions were used as the basis of the neural network correlation. With an initial database containing 1019 measurements, the correlation yield... |
