摘要
针对新建的中国计量学院回流式低速风洞,利用皮托管对试验段的气流流动特性进行详细的研究.实验确定了风机工作频率与气体流速间的关系,并对风洞试验段的流场均匀性进行了分析.
A low speed closed circuit wind tunnel has been newly constructed on the campus of China Jiliang University. The characteristics of airflow in the test section of the wind tunnel have been investigated in detail by using Pitot tube. The relation ship between the working frequency of wind engine and airflow velocity has been determined. The uniformity of flow in the test section of the wind tunnel has also been analyzed.
