摘要
本文给出将现有湍流模型用于浮力流的若干修正方案;分别运用湍流粘性系数模型和雷诺应力模型及它们的浮力修正型、双流体模型对几种典型的浮力流进行计算机模拟;最后提出选用浮力流湍流模型的建议.
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.
