摘要
应用标准形式的ｋ－ε湍流模型，对具有逆向压力梯度的渐扩通道内两股等温或不等温射流的湍流流动与混合进行了数值模拟。结果表明，时均速度场与温度场的计算结果与实验测量数据相符合。
The
standard form of the k ε turbulence model was utilized.Numerical simulations were performed
for the turbulent flow and mixing of two coaxial isothermal or non isothermal jets in a diverging
duct with adverse pressure gradient. The calculated distributions of the time averaged gas
velocity and temperature were compared with the measured test data.
