The experimental study of non-equilibrium gas flows requires the design, creation and operation of specific facilities and the development of particular diagnostic techniques. Most experiments are carried out in ground facilities which can generate non-equilibrium flows. These facilities generally require important equipment and investment. The essential purpose is to create high enthalpy gas flows undergoing more or less intense perturbations shock wave, rapid expansion , so that, physical and chemical processes evolve on a time scale equal to or longer than the characteristic flow time scale. Two types of facilities are described here, depending on the type of phenomena or the processes analysed, shock tubes and shock tunnels. Thus, if the analysis of the physical and chemical processes themselves is considered as essential, simple facilities, such as shock tubes generating one-dimensional, non-dissipative flows are to be used. On the contrary, if the simulation of the conditions of real flight is required, facilities such as shock tunnels generating hypersonic flow around various bodies must be used.
