摘要

给出了沿康达面注入环形径向射流的通道内流动的数值研究结果。为了描述气体介质的流动，将二维轴对称reynolds -average Navier-Stokes （RANS）方程与半经验k -ω SST湍流模型方程结合使用。研究了总压和径向射流宽度对速度和静压分布的影响，描述了射流在亚临界和超临界压力下局部结构的变化。

Numerical Study of Flow Structure in an Axisymmetric Channel with Injection of a Radial Jet along the Coanda Surface

The results of numerical study of the flow in a channel with an annular radial jet injected along the Coanda surface are given. To describe the flow of the gas medium, the two-dimensional axisymmetric Reynolds-averaged Navier-Stokes (RANS) equations are used in combination with equations of the semi-empirical k–ω SST turbulence model. The effect of the total pressure and the width of radial jet on the velocity and static pressure distributions is studied and changes in the local structure developed at the sub- and supercritical pressure in the jet are described.
