Abstract:    The fluid dynamic and the gas-liquid mass transfer characteristics of trickle-bed reactors were revisited and their quantification methods reevaluated based on extensive experimental historic flow data bases (22,000 experiments) set up from the open literature published over the last forty years.  The state-of-the-art of trickle bed fluid dynamics was summarized and a set of unified and updated estimation methods relying on neural-network-dimensional analysis-phenomenological hybrid approaches were discussed.

 You can get the code.zip   file  to compute (Fortran) with neural models given in Table 2 of the paper

Trickle-bed simulator to simulate mass transfer, pressure drop, liquid holdup and flow regime transition.

The neural correlations were  developped with the software NNFit
