摘要
先介绍了两种测量风洞稳速压控制系统风速反馈值的常用方式-单点风速测量法和多点静压落差法,并对其特点和应用场合进行了分析;然后对多点静压落差法进行数学建模,给出了静压落差与风洞试验段中心点风速的关系;最后用一个工程实例说明此方法在实际风洞设计中的应用。
This paper introduced two wind-speed measurement methods in wind tunnel＇s speed control system,single-point wind speed measurement method and multi-point static pressure meth-od,as well as their features and applications.Then mathematical model was established for the latter method and formulas relating static pressure to wind-speed at test section center were given.In con-clusion,this method was applied to one real-world wind-tunnel design project.
