环形射流作用下吸气流动的临界射流速度研究

The Research on Critical Velocity of Sucking-airflow Affected by Annular Jet

对环形射流作用下吸气流动的临界射流速度进行了全面研究 .在笔者设计的实验台上 ,测量不同工况下的临界射流速度 .各种工况包括不同的吸气量、叶片数和吹气口宽度等技术参数 .并应用回归的方法对所得的实验数据进行分析、处理 ,得到临界射流速度与相关因素之间的数量关系 。

A thorough research on the crucial velocity of sucking airflow affected by annular jet is conducted. The crucial velocity in different conditions on the designed experiment appliance is measured, including different quantity of sucking air, different siges of blade and different width of pushing air inlet. By using regression method, the relationship between critical velocity and different conditions is established, and an important parameter for research and utilization of this kind of airflow is proposed.
