Abstract:

The gas flow field on rotating stream tray was studied by using FLUENT CFD software. By the k-ε gas turbulence model and SIMPLER algorithm，a 3-D gas flow field on rotating stream tray has been obtained by  third-order calculation. The numerical results agree well with experiment data at small inlet flow rates. A negative-velocity zone is found in gas flow field. As height increases，the tangential velocity decreases，and radial velocity decreases more significantly.
