Babenko O. The improved method of calculating an ejection device in gas supply system

Object of research - gasdynamic processes ejection devices based on the properties of a real gas. The aim is to improve the methods of calculation of the single-phase gas ejector with a cylindrical mixing chamber and supersonic nozzle. Research methods - analytical methods for one-dimensional theory of motion based on the laws of conservation of momentum, energy and mass, gas-dynamic functions of a real gas, the ratio of thermodynamics gas motion. The proposed technique can be used to develop new and existing recalculation ejection device in the gas supply system. The main results of the thesis are included in the work program of the discipline "Gas" KNUCEA. Introduction of improved methods conducted in the Institute of Transport project practice gas "Tehdiagaz" on Skorobagatkovskom field. Scientific novelty of the study is to: improve calculation method based on the ejector gas-dynamic functions, which differs from the existing based on the properties of a real gas, which improves the accuracy of the calculation parameters on the outlet of the ejector and its structure; proposed a system of equations for calculating the characteristics of the gas ejection device; gasdynamic equations specified functions of a real gas for the characteristic values of the relative velocity; obtain relations between the gas-dynamic functions of a real gas.
