An inviscid flow model is presented to gain a basic understanding of the reflection of a swept oblique shock from a planar wall. The analytical model is constructed to describe the fundamental influence of sweep on this shock configuration, which has been commonly studied as an unswept non-dimensional shock boundary layer interaction (SBLI). Transformation of model parameters into a plane perpendicular to the sweep angle reduces the resultant flow to a two-parameter system. An equivalency between this configuration and others commonly assessed is presented with advisory notes on the definition of effective coordinate systems. Inviscid shock detachment has been associated with the onset of quasi-conical SBLI spanwise development; see (Settles & Teng, AIAA J. , vol. 22 (2), 1984, pp. 194–200). Its occurrence for this SBLI configuration is determined for a range of conditions and compared to experimental observations of swept SBLIs claiming cylindrical/conical similarity scalings. Finally, influence of a zero-mass flux plane associated with typical experimental and numerical analyses is presented with an accompanying model for the shock structure. While this paper serves as a useful resource when designing swept impinging oblique SBLI studies, it also provides a vital benchmark for this complex configuration and helps to unify various SBLI configurations that are often analysed in isolation.

扫掠斜激波反射的无粘性分析

提出了一个无粘性流动模型，以获得对平面壁的扫掠斜激波的反射的基本理解。构建分析模型来描述扫掠对这种激波配置的基本影响，这通常被研究为未扫掠的无量纲激波边界层相互作用 (SBLI)。将模型参数转换为垂直于扫掠角的平面将合成流量减少到双参数系统。此配置与其他通常评估的配置之间的等效性通过有关有效坐标系定义的咨询说明提供。无粘性冲击脱离与准锥形 SBLI 展向发展的开始有关；参见（Settles & Teng, AIAA J. , vol. 22 (2), 1984, pp. 194–200）。这种 SBLI 配置的出现是在一系列条件下确定的，并与声称圆柱/圆锥相似性标度的扫描 SBLI 的实验观察结果进行比较。最后，与典型的实验和数值分析相关的零质量通量平面的影响与冲击结构的随附模型一起呈现。虽然本文在设计扫掠冲击斜 SBLI 研究时是有用的资源，但它也为这种复杂的配置提供了一个重要的基准，并有助于统一经常单独分析的各种 SBLI 配置。与典型的实验和数值分析相关的零质量通量平面的影响与冲击结构的随附模型一起呈现。虽然本文在设计扫掠冲击斜 SBLI 研究时是有用的资源，但它也为这种复杂的配置提供了一个重要的基准，并有助于统一经常单独分析的各种 SBLI 配置。与典型的实验和数值分析相关的零质量通量平面的影响与冲击结构的随附模型一起呈现。虽然本文在设计扫掠冲击斜 SBLI 研究时是有用的资源，但它也为这种复杂的配置提供了一个重要的基准，并有助于统一经常单独分析的各种 SBLI 配置。
