Abstract: The effect of temperature on the hydrodynamics of trickle-bed liquid cyclic operation was studied. The trickling-to-pulsing transition in cyclic operation was compared to spontaneous transition in constant-throughput flow, as well as the corresponding pulsing flow regimes. The effect of temperature on and , and on liquid holdup and shock wave plateau time, was assessed for (non-)Newtonian liquids. The effects of temperature and superficial gas velocity on pulse velocity and pulse frequency were evaluated for pulsing flow in cyclic and constant-throughput flows. With increased temperature, shifted to higher gas and liquid velocities; however, the modified Charpentier–Favier diagram still adequately captured both and evolutions with temperature.
