An oblique shock wave is a shock wave that, unlike a normal shock, is inclined with respect to the incident upstream flow direction. It will occur when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. The upstream streamlines are uniformly deflected after the shock wave. The most common way to produce an oblique shock wave is to place a wedge into supersonic, compressible flow. Similar to a normal shock wave, the oblique shock wave consists of a very thin region across which nearly discontinuous changes in the thermodynamic properties of a gas occur. While the upstream and downstream flow directions are unchanged across a normal shock, they are different for flow across an oblique shock wave.

  • 斜激波（英語：oblique shock）是指相对于来流方向倾斜的激波，与正激波相对。超音速流绕角转向并压缩时会产生斜激波。来流流线经激波后转过的角度相同。制造斜激波常见的方法之一是在超音速流中放置楔形物。与正激波相似，气体热力学性质在穿过非常薄的斜激波区域时有近似不连续的变化。但与正激波不同的是，正激波不会改变来流方向，而斜激波则会。 通过伽利略变换，可以将斜激波转化为正激波。

It is always possible to convert an oblique shock into a normal shock by a Galilean transformation.
