| 摘 要： | 本文研究了二元风洞侧壁抽气问题。文1]曾考虑了抽气对风洞内无粘主流和有粘边界层的双重作用。本文研究则进一步包含了侧壁开孔率和开孔方向的影响,更为全面地描述了有侧壁抽气时风洞内的流动,并从理论上探讨了消除侧壁干扰的抽气控制问题。

| Abstract: | This paper studies the sidewall suction in a. two-dimensional wind tunnel. Ref. 1] presented an analysis to the dual effect of suction on the invisid main flow and the viscous boundary layers. The investigation presented in this paper further considers the effects of porosity and suction orifice inclination, and therefore, more perfectly describes the influence of the sidewalls on the flow in a wind tunnel. Moreover, ..he control of the sidewall suction is explored theoretically so as to eliminate the interference from the sidewalls. |
