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 influence of non-uniform inlet field of total pressure on the distribution of secondary losses in flat nozzle grids of different types is considered. According to the results of the studies, the character of secondary flow distribution depends on the type of profile and the nature of the inlet full pressure diagram. The presence of even a minimal gradient in the total pressure at the inlet changes the type of aerodynamic characteristics of the nozzle grid. Not taking this factor into account can lead to the necessity to refine the entire turbine, which will increase the development time. |
