| Abstract: | Some modifications of the present turbulence models for predictions of
buoyant flows are presented.Several typical buoyant flows are predicted by
use of the modified turbulence viscousity model,Reynolds stress model and
the two-fluid model of turbulence.Finally,the proposals are given for choo-
sing adequate turbulence models of buoyant flows. |
