摘要: 已往对气泡射流的理论研究,主要集中在半经验和积分模型方面,对流动结构揭示很少。给出了气-液两相流两方程湍流模型。为了加深对气泡射流规律的理解和为数值计算建立对比基础,提出了一组参考量,对Sun和Faeth的试验资料进行了整理。

Abstract: For the study on the behavior of bubbly jets in static environment, it was mainly used the integral model in the past. And there was a little information on the structure of this kind flow. A two-equation turbulence model for two-phase flows is proposed in this paper. In order to understand the law of bubbly jet and give the contrast base between the experimental data and numerical calculation, the experimental data of Sun and Facth is arranged by a set of reference scale found by auther.
