摘要
本文介绍了一种风洞固定地板边界层厚度控制新方法。风洞试验结果比较表明,这种方法不但能显著降低地板边界层厚度,而且边界层控制装置对风洞气流干扰较小,流场较均匀,气流品质较好。与国内外现有的风洞地板边界层厚度控制方法相比,这种方法颇具特色。
A new method is described in this paper for boundary layer thickness control on the fixed ground plate in the wind tunnel. The ground plate with this control is named ISS (Internal-Suction-Slotted) ground plate. From the experimental results of the flow over the ISS ground plate in a 3m×3m wind tunnel it is indicated that such control method can not only effectively decrease the boundary layer thickness, but also bring smaller interference to the flow field quality. This method is recommendable in comparison with others for the boundary layer thickness control on ground plates in wind tunnels.
