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 paper presents 2D modeling of flow in a turbine using Logos AeroHydro and Ansys CFX software. The influence of turbulence models on the kinematic outflow angle and profile loss coefficient was investigated. Two grid models were applied: one for wall functions implementation and another with sufficient resolution for viscous sublayer. The results demonstrate that both software packages adequately describe the flow characteristics. The SSTmodel turbulence model showed the best agreement with experimental data in the specified operating range. For the kinematic outflow angle, minimal deviations were observed within the defined operational regime. Areas of overestimated losses were identified, requiring further investigation using unsteady simulation methods. |
