WANG Huajin, XIE Wanni, SUN Yongli, et al. CFD simulation of hydrodynamics of orthogonal wave type tray[J]. CIESC Journal, 2015, (12): 4743-4750.DOI: 10.11949/j.issn.0438-1157.20150409.
was developed. A 3D transient computational fluid dynamics model in the Eulerian-Eulerian framework is developed to predict the hydrodynamics of OWT tray. Drag force is mainly considered as the interphase momentum exchange term and calculated using the Krishna correlation. Simulated clear liquid height is in good agreement with the experimental value. The hydrodynamics including pressure drop
liquid velocity and gas-liquid distribution under various gas and liquid rates are investigated. Comparison with sieve tray without downcomer shows that OWT tray has an improved turn down ratio and stability.
