Study of Changes in Gas Flow Parameters in a Tube with Gradually Reducing Cross-Section Using Ansys Fluent Application

This paper presents the results of a study investigating changes in airflow parameters such as pressure and velocity as the flow moves through a converging nozzle, using the Ansys Fluent software platform. Converging nozzles are widely used in the jet engines of subsonic aircraft. The study analyzes the behavior of airflow parameters within this type of nozzle using Ansys Fluent and compares the findings with theoretical and experimental results. This approach enables the determination of specific parameters under varying conditions and identifies the underlying causes of these parameter changes.
