摘要
论述了在 1 m量级风洞中进行汽车模型实验的有关技术问题 ,分析了厢式货车安装导流罩等气动附件后 ,气动阻力特性的变化情况 ,为在小风洞中进行汽车模型实验开辟了一条路径 。
The paper represented some technical problems encountered in experiments of auto model in a wind tunnel with one meter level. A new way for the tests of auto model in lower level wind tunnel was developed. The varieties of aerodynamic resistance with changes of the shape, structure of the cover and its geometric locations were analyzed after mounting conducting fluid cover on the van model. Three kinds of vans with covers and their effects on decreasing resistance as well as situation of saving oil were introduced and observed. An effective method for reducing resistance, energy conservation of van was provided.
