| Abstract | ||
| Distillation Column is one of the eldest and important separation equipments which many new designs and various changes in its internals are still being made for increasing its performance. In this research with utilizing computational fluid dynamics, sieve tray hydraulics in experimental scale has been simulated in two phase and three dimensions in Eulerian frameworks by FLUENT 6.3 commercial software. And the simulation have been validated with Krishna et al. (1999) experimental and simulations results. Then simulating with RSM and k-e in three forms of Standard, Realizable and RNG turbulence models, the results have been discussed and compared and has been demonstrated that the RNG model predicts lower clear liquid height which are closer to the experimental results. | ||
