Abstract: Numerical simulation of three dimensional gas flow field in the corrugated plate packing was investigated using the Fluent software and RNG turbulence model. The results showed that, after the gas enters in the bottom of packing, most of the gas went through wave of the plate, with higher gas velocity and lower pressure drop; while only a small part of gas entered in the peak wave of corrugated plate, and then flow tortuously towards the outlet, with smaller velocity and higher pressure drop. The simulation value of dry plate pressure drop agreed well with the Billet model prediction and experiment data in different gas kinetic energy factors. For the ideal corrugated plate packing model, when the gas arrived to the tower wall, it would change direction to flow along the corrugated inclination of the adjacent plate; however, this type of packing would appear wall flow phenomenon in practical application. Research in this paper could be used in guiding the construction, modification and application of corrugated plate packing.
