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: | The tightening of environmental standards for NOx emissions requires improvement of design methods for gas turbine power units. One effective way to reduce emissions is to burn poor fuel-air mixtures, but this increases the risk of flame stall. Addition of hydrogen improves combustion stability but can lead to flame slippage in the burner. In this paper, unsteady combustion processes of methane-hydrogen mixtures are investigated using numerical modeling. A model based on the TFC method, detailed chemical kinetics and a modified presumed-PDF approach for calculating NO formation is developed. The results will provide a tool for the design of low-emission combustion chambers. |
