摘要
通过实验的方法,实测了双进口涡向起旋圆管内旋转流场,得出圆管内各断面上旋转流场分布、旋转流的速度分布、压力分布的特点,并分析拟合得出旋流速度指数衰减的公式。
The characters of swirling flow are the most important for studying the effect of swirling flow enhancing heat transfer and separating.By the means of experimental testing method,the flow distributions of swirling flow by double helical inlets are illustrated.By discussing the flow distributions,the velocity and pressure distributing characters are presented.The decaying law of swirling flow is formulated.
