Experimentation and Numerical Investigation on Supersonic Ejector with Axial Pressure Sensor

摘要

This work is dealing with the investigation of the air flow inside a supersonic ejector.The main goal of this study is to show,influence of an axial pressure probe on the local flow characteristics.2D axisymmetric and 3D CFD models are developed. Several turbulence models are tested.The 2D axisymmetric modelling with an intrusive probe is essential for understanding the flow phenomena. Further,the numerical simulations show a significant attenuation of the shock waves due to the pressure probe insertion.The 3D CFD model confirms the results obtained with the 2D axisymmetric model and gives results closer to experimental data.
