In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in … See more Shock waves can be: Normal At 90° (perpendicular) to the shock medium's flow direction. Oblique At an angle to the direction of flow. Bow Occurs upstream of the front (bow) of a blunt object when the … See more In elementary fluid mechanics utilizing ideal gases, a shock wave is treated as a discontinuity where entropy increases abruptly as the … See more Shock waves can form due to steepening of ordinary waves. The best-known example of this phenomenon is ocean waves that … See more Below are a number of examples of shock waves, broadly grouped with similar shock phenomena: Moving shock • Usually … See more The abruptness of change in the features of the medium, that characterize shock waves, can be viewed as a phase transition: the pressure-time … See more Oblique shocks When analyzing shock waves in a flow field, which are still attached to the body, the shock wave which is deviating at some arbitrary angle from … See more A shock wave may be described as the furthest point upstream of a moving object which "knows" about the approach of the object. In this description, the shock wave position is defined … See more Web3 Dec 2014 · The shock wave begins to expand outwards as more plasma arrives and has its kinetic energy converted to thermal energy. The shock is very efficient at heating – the thermal energy of the material is close to what you’d expect from the kinetic energy of the flows, heating the plasma to around 10 million ‘C.
