This monograph treats, for the first time, major aspects of gas dynamics of nozzles from a general point of view. Its outstanding feature is the pre- sentation of the modern theory of gas flows and modern analytical and nu- merical methods, together with numerous examples of practical applications. At the same time, quite diverse physico-chemical processes, such as disso- ciation and recombination, relaxation of vibrational degrees of freedom, two-phase flows wi th phase trans formati ons and e 1 ectromagneti c i nf1 uences, are considered. The material is presented in such a way as to help...
