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: | Numerical simulation was chosen as a research method. Computational model has been verified and configured based on the results of previous tests. The results of numerical modeling showed that the proposed design of the rotor blade tip squealer allows to reduce the kinetic energy losses in the rotor blade by more than 11 % (rel.), increasing the efficiency of the high pressure turbine stage by more than 0,27 % (abs.). The positive effect was achieved by changing the structure of secondary vortex structures, dividing large and intense vortex into small ones with lower intensity. |
