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: | In this paper, a study was conducted on the influence of various geometric parameters of perforation cooling holes of a modern annular compressor station on the efficiency of the cooling system. The efficiency analysis was performed using CFD. The following geometric parameters of the cooling system holes were changed: angles of inclination of the holes; angles of rotation of the holes; types of hole geometry; the order of the holes (linear and staggered). The efficiency parameter was taken to be the value η, which is defined as the ratio of the difference in the temperature of the hot air at the inlet and the adiabatic wall temperature to the difference between the temperatures of the hot and cold air. |
