温差射流中热绕流现象的数值模拟

A Numerical Simulation of Thermal Roundabout Flow Phenomenon in Non-isothermal Jet

数值模拟了同心圆管内冷、热气流的掺混 ,得到了整个射流场中速度分布规律和掺混角变化规律 ,分析了冷、热流体掺混中的热绕流现象。这对存在冷、热射流流动的工程问题的研究提供了数值结果。

The mixing of non-isothermal air current in homocentric circles is simulated, the velocity distribution in whole flow field and the change of mixed angles are obtained , The thermal roundabout flow phenomenon in mixing of non-isothermal air current was analyzed. Which provide with numerical result for engineering-research with non-isothermal jet.
