The shock propagates with a wave front which is normal (at right angles) to the direction of flow. The speed of the shock is a function of the original pressure ratio between the two bodies of gas. Moving shocks are usually generated by the interaction of two bodies of gas at different...

Even the Earth, shielded by its own magnetic field, pushes a shock wave to a distance of about 20 Earth radii as a head wave in the solar wind. In several ways shocks come into existence by artificial generation, such as with nuclear or chemical explosions, with the sonic boom of super...

If a duck is paddling faster through a pond than a water wave can propagate, a shock separates the wake from the undisturbed water. In both cases the disturbance and with it the shock is moving, and thus the shock is called a traveling shock. Standing shocks also form: in a river, a...
After theshock wavehas propagated through the air someradial distancefrom the center of explosion (also known as the ‘center of burst’), the air immediately behind the shock front is highly compressed relative to ambient conditions, and behind thiscompressed air, at a distance known as the po...
The unsteady flow following the shock wave was imaged and revealed these reverse shocks in the vortex ring1. Vortex rings have also been shown to have mini shocks inside the rings as they travel through air. As a vortex ring approaches a square plate, a mirror effect occurs. A vortex ring...
