Study on the Behavior of Bubbly Jets in Static Uniform Environment, 1, Mathematic Model and Experimental Data Analysis

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.
