The research goal is mathematical models formulation of gasdynamic flows in presence of phase transition and non-equilibrium physico-chemical transformations what are reasonable for installation on up-to-date PC, engineering of software and pieces of experimental equipment and studies of laws of high-temperature processes. The research methods are calculated-analytical and experimental. Mathematical models are built, calculating algorithms and software for calculations of gas dynamic flows through channels and tubes in occurring phase and non-equilibrium physical and chemical transformations are developed. Scientific novelty of the results obtained is to reveal new regularities of gas dynamic flows using computations in occurring phase transitions and non-equilibrium physical and chemical transformations. Conditions of combustion of a hydrocarbon jet through channel depending on the initial parameters and the position of the cross-section of an artificial ignition are analyzed. Principal specific features of interaction between a supersonic turbulent off-design jet and a cocurrent subsonic flow through convergent channel are presented. Specific features of the denotation ignition of combustible mixtures through closed channel with a single reflection and multiple overreflections of shock waves from its walls are studied. The basic regularities of the influence of the mass fraction of water in an air-drop mixture, a distributed supply of mass and power on the self-oscillation parameters occurring through channel with the mixture efflux from reservoir through channel in medium with a given pressure are examined. The specific features of transition processes of the gas-filling fluids flows with gas releasing in elements of complicated manifold systems are studied. Applications: gas dynamic processes in technological equipment for aircraft and space technologies, power engineering, engine manufacturing, chemical industry. Programs for calculating of an air equilibrium flows of propellant combustion products in launching the product from the launching tube and gas dynamic loads on launchers, when supersonic nozzles are launched over them, are used at Yuzhnoye State Design Bureau for design calculations of spacecraft launching for various starting devices.
