图1. 开放式风洞示意图
长7.5 m,宽、高各1 m的方形风洞,进风一头由梳风栅引导风向,另一头有一个直径为0.9 m的轴流式风扇,该风扇可在工作空间内形成稳定的单向0—8 m·s-1无级调节的风
风速由风速仪测定后,在微机的屏幕上显示风速值

Fig. 1. Schematic diagram of open wind tunnel
A square wind tunnel with a length of 7.5 m, a width of 1 m and a height of 1 m. One end of the air inlet is guided by the comb grid, and the other end has an axial-flow fan with a diameter of 0.9 m. The fan can form a stable one-way 0-8 m·s-1 stepless adjustable wind speed in the working space
After the wind speed is measured by anemometer, the wind speed value will be displayed on the screen of microcomputer
