What happens during rarefaction?
Rarefaction is the reduction of an item’s density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).

Rarefied gas dynamics is based on the kinetic approach to gas flows. Thus Maxwell gave the origin to the kinetic theory of gases. Then, in 1872 Boltzmann [2] deduced the kinetic equation which determines the evolution of the distribution function for gaseous systems being out of equilibrium.
