高速流绕平板边界层特性研究

Experimental Study of Boundary Layer Features on a Flat Plate in High Speed Flow

本项高超声速流绕平板的边界层特性实验研究在中国航天空气动力技术研究院(CAAA)的炮风洞中完成.为了研究分离流动特性,选择了一项实验研究,通过实验分别提供绕模型的附着流动与分离流动实验结果.其中第1个模型为顺流平板,第2个模型为平板上安装突起物,它们分别对应附着流与分离流动.文章专题研究平板绕流,为附着流,它是分离流动的基础.

An experimental study on boundary layer features in hypersonic flow had been done. The tests had been per- formed in the gun tunnel at China Academy of Aerospace Aerodynamics （CAAA）. In order to investigate the characteristics of the separated flow field, there were two parts of work have to be done, the attached flow and separated flow over the mod- el surface. The first model was a fiat plate. The heat flux distributions along the centre line of the fiat plate had been meas- ured by thin film transducers. The results have published in this paper. It will be as a basic reference （attached flow） to compared with the results of the second model （the blunt fin mounted on the fiat plate） for separated flow.
