Web13 May 2024 · Depending on the shape of the object and the speed of the flow, the shock wave may be inclined to the flow direction. When a shock wave is inclined to the flow direction it is called an oblique shock. On this slide we have listed the equations which describe the change in flow variables for flow across an oblique shock. WebVelocity Shocks Velocity shock has two components: intensity, usually measured in g's (1 standard g = 9.80665 m/s 2 ), and duration, measured in milliseconds.
