Flow regimes for nonfoaming and foaming two‐phase downflow through catalyst beds are correlated in terms of the superficial volumetric gas‐to‐liquid ratio and a force ratio relating inertia plus gravity forces to viscous plus interphase forces. In the pulsing flow regime, the frequency of pulses leaving large (29.2 cm) and small (6.58 cm) diameter beds is correlated with the flow map coordinates.
