TJ—Ⅱ对汽车模型风洞地面边界层控制机理和控制设备研制

A Discussion on Boundary Layer Control of TJ-I Automotive Model and Control Equipment

本文叙述了对同济大学TJ—Ⅱ号汽车模型风洞地面边界层利用抽吸法进行修正的过程。通过在以TJ—Ⅱ风洞为原形的1:6模型小风洞进行模拟对比实验,得出具有最佳抽吸效果的一系列参数,并应用于TJ—Ⅱ风洞,取得良好效果。

This paper describes the process of controlling the boundary layer of TJ -II scale - model automotive wind tunnel with suction method,The optimal suction parameters were obtained through a 1 : 6 small wind tunnel,which TJ- II tunnel simulated. The result has been applied on TJ-II wind tunnel and good effects were observed.
