二维线性浮力羽流特性的研究

Study on the deterministic properties of line buoyant plumes

通过对二维线性浮力羽流的理论分析，得到了羽流温度分布，速度分布以及羽流宽度和卷吸常数的表达式。并用实验的方法测量了由线性火源产生的二维线性浮力羽流的温度和速度变化。

A theoretical analysis of line buoyant plumes was made. The temperature and velocity distributions, the width and entrainment coefficient of line buoyant plumes were obtained. The experimental measurement of temperature and velocity distributions on line buoyant plume center lines were reported. The comparison shows that the theoretical analysis and experimental results agree well.
