Shock wave temperature
In a shock wave the properties of the fluid (density, pressure, temperature, flow velocity, Mach number) change almost instantaneously. Measurements of the thickness of shock waves in air have resulted in values around 200 nm (about 10 −5 in), [8] which is on the same order of magnitude as the mean free … See more 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 … 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 … 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 as the boundary between the zone having no information about the shock … 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 upstream flow velocity exceeds Mach 1. 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 form breakers on the shore. In shallow water, the … See more http://brennen.caltech.edu/fluidbook/basicfluiddynamics/Compressibleflow/shockwaves.pdf
