| Abstract: | A three-dimension computational fluid dynamics(CFD) simulation was carried out for the liquid flow field on a combined trapezoid spray tray(CTST) with 1 000 mm of diameter based on its operating characteristics.The distribution features of three-dimensional liquid flow field on the plate were obtained through calculation.The simulation results are in good agreement with the experimental data.It shows that the model can well describe and predict the liquid flow field on CTST.The liquid flow fields of sieve tray and CTST were simulated respectively,in which the liquid back mixing of CTST is obviously smaller than that of sieve tray. |
