Samara University Repository
Welcome to the Samara University repository!
This is an open electronic archive created to preserve and disseminate the scientific results of our university. The works of researchers, faculty members, and students are available to everyone for academic and research purposes.
The repository contains dissertations, research articles, educational and methodological materials, monographs, and regulatory documents. The collections cover a wide range of fields: from aerospace technologies, engine engineering, and computer science to history, linguistics, mathematics, and ecology. The archive brings together the scientific heritage of the university, including materials prepared during the period of Samara State Aerospace University and Samara State University.
Looking for publications by author, title, date, or subject? Full-text search will provide relevant results. Want to explore the academic life more closely? Browse materials by the universityâs organizational units.
Descriptions of all publications and articles available in the repository can be found in the libraryâs electronic catalog. Staff and students can log in via the menu "Login -> My Resource Archive" using their personal account credentials (SSAU_id).
Use the archive for study, research, and professional development!

| Abstract: | Changes of a design of the GTU combustion chamber, have to improve characteristics of the engine. It is possible to apply the numerical analysis to the fast choice of a design. In this work were applied modern the sredst of computing hydrodynamics. The model of burning Finite Rate/Eddy Dissipation with the simplified kinetic mechanism was used. Were applied two generalized chemical reactions. Thermal, gasdynamic and issue characteristics of several modifications of GTU NK-38ST combustion chambers were as a result received. Calculation was carried out for nominal power setting. parameters on an entrance to the combustion chamber changed with change of ambient temperature. Temperature was both positive and negative. Comparison of the numerical results considered modifications is carried out. The analysis is carried out on the maximum completeness of combustion, the minimum concentration of CO and losses of total pressure. Application of the simplified approach gave approximate values of parameters. The most opt |
