The objectives of the study are: clarification of the working process and the method of calculating the basic parameters and characteristics of the jet-reactive expansion engine; investigation of the influence on the structure of the spin gas flow characteristics and axial-radial impeller of a centrifugal compressor; numerical simulation and experimental study of the flow characteristics of the gas and the labyrinth seals. Methods of research - theoretical methods (mathematical and numerical modeling), computer and physical experiments. In the refined mathematical model of the working process and the method of calculation of parameters and characteristics of the jet-reactive expansion machine, with the help of modern software systems is simulated and the numerical study of gas flow in the jet-reactive expansion machine inlet guide vanes and axial-radial wheel of a centrifugal compressor in a labyrinth seals for turbomachinery, experimental studies of the labyrinth seals. The results can be used in different sectors of the economy and society in the gas, chemical and other industries, utilities and others. Product Description popup.authors Ігнатенко В.М.
