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 modifying the boundary layer of wind tunnel of TJ-II model of Tongji University by suction method. A series of parameters with the best suction effect were obtained by simulating the 1: 6 model small wind tunnel with the TJ-Ⅱ wind tunnel as the prototype. The results were applied to the TJ-Ⅱ wind tunnel and achieved good results.
