CFD SIMULATION OF FLOW REGIMES IN THE SUPERSONIC WIND TUNNEL OF THE FACULTY OF AERONAUTICS
2014
Three cases of the working regime of the supersonic wind tunnel of the Aeronautical Faculty are simulated by using CFD (computational fluid dynamics) program ANSYS CFX. CFD simulation results of the wind tunnel are in agreement with existing technical documentation and experiences with the wind tunnel\'s operation and provide detailed information about inlet airflow speeds, required strength of the models in the test section and requirements of the vacuum pump. It is concluded, that CFD program is able to describe the airflow in Laval nozzle with supersonic speeds, according with published theory of quasi-one-dimensional and two-dimensional airflow.
