cfd simulation of concap tray hydrodynamics

this research includes both experimental and cfd investigation in the hydrodynamic behavior of a new type of column tray introduced as “concap” tray. the proposed column tray is used in contactor columns especially in stripping columns. the hydrodynamics of this concap tray is investigated in a 1.2m in diameter column. using air-water system, the experiments were performed for different liquid and vapor loads at constant ambient temperature and pressure. the clear liquid height and total pressure drop were measured. the results were compared with the experimental data of a valve tray in the same column simulator rig. the total pressure drop and clear liquid height of concap tray were similar to a valve tray, having equal 14% open holes area. liquid velocity distribution on the tray has been predicted by cfd and is reported.
