Which software is used for the hydraulic calculations of extraction towers (liquid-liquid extraction)?

In particular, what are the theories regarding liquid flooding in sieve plate towers? It seems that there is very little information on this topic
This is very simple; it can be calculated without any software. First, the diameter of the standard droplet is determined based on the surface tension of the dispersed phase. Second, the upward or downward velocity of the droplets is calculated using the density difference. Third, the flooding rate is selected, along with the flow velocity of the continuous phase, and then the diameter of the tower is calculated. In liquid-liquid extraction, the so-called flooding occurs when the flow rate of the continuous phase is greater than that of the sulfuric acid droplets in the dispersed phase; generally, the flow rate of the continuous phase is kept less than half of that of the dispersed phase, meaning that the flooding ratio is less than 0.5.
