Kate Gosselin recently walked onto the set of the View donning a new hairstyle. Shock. In place of her well-known no-nonsense Angle cut were soft waves.

The touch point deviates eastward with respect to the central normal of the shock source, and the deviation Angle increases during the outward propagation of the shock system.

Flow field of shock wave passing by right Angle and wedge is analyzed using numerical method and numerical interference technique combining with experimental interferograms.
