本文对正激波/湍流边界层干扰的实验进行了分析。实验是在狭窄风洞中的凸壁上进行的，壁马赫数Afw = 1.47，雷诺数Re，x 1<T = 5.5; 9.7; 13.1; 15.3。实验表明，由于这种相互作用，分离流场是高度三维的。静壁压测量、皮托管和静压测量以及 *Zm图片支持并补充了基于油流±ZL的流场结构拓扑分析。三维分离流场结构与温度的非唯一相关性。强调流型。分离流场的复杂拓扑结构进行了分析，表现出明显的不对称性与雷诺数的增加。
An experiment on normal shock wave/turbulent boundary-layer interaction is analyzed. The experiment is performed on a convex wall in a narrow wind tunnel at a wall Mach number Afw = 1.47 for the Reynolds numbers Re, x 1<T = 5.5; 9.7; 13.1; 15.3. The experiments indicate that due to this interaction the separated flowfield is highly three-dimensional. Static wall pressure measurements, pitot and static pressure surveys and *Zm pictures support and complement a topological analysis of the flowfield structure based on oil-flow ±ZL. The non'unioue dependence between a three-dimensional separated flowfield structure and ,ts ol. flow pattern is emphasized. The complex topology of the separated flowfield is analyzed exhibiting a pronounced asymmetry with increasing Reynolds number.
