On the basis of a large data bank consisting of more than 2,600 experimental
results published for cocurrent upflow
fixed bed reactors, a state-of-the-art correlation for the prediction of
external liquid saturation was proposed. The correlation relied upon
combination of dimensional analysis and artificial neural networks which
allowed identification of 6 most expressive dimensionless groups. Robustness of
proposed correlation was assessed by testing it on a huge test data file, and
the limitations of the literature correlations with regard to their
generalization capabilities were demonstrated.
