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: | This study compares analytical and CFD (ANSYS Fluent) approaches for modeling gas flow in a rocket engine. The analytical method assumes ideal 1D flow, while the CFD model accounts for viscosity and 3D effects. Key results:• Pressure/temperature deviations <7%;• CFD reveals underexpanded jet flow;• Model validity confirmed for preliminary nozzle design.The work demonstrates CFD's superiority in capturing real flow features while maintaining analytical solution accuracy. |
