Аннотация: Microjets are widely used for the mixing of gases and the protection of surfaces from chemically aggressive and high-temperature media. The basic technological characteristics of jets in this case are their penetration capability and the intensity of mixing processes. The goal of the present chapter is to study the structure and stability of microjets. The overview of the works on the study of the gas dynamics of subsonic and supersonic mini- and microjets is given in Sect. 2.1. As tools used in experimental investigations are also very important, they are described in much detail. Diagnostic methods and the results of studying subsonic plane jet stability are described in Sect. 2.2. Experiments aimed at studying the structure and stability of supersonic axisymmetric microjets and the results obtained therein are discussed in Sect. 2.3. Much attention is paid to the techniques used to obtain experimental data. Finally, the problem of microjet modeling with the use of commonly used similarity parameters is discussed in Sect. 2.4. © 2018, Springer International Publishing AG, part of Springer Nature.
