NACA Airfoil at transsonic velocity

About this project

Hello Simscale Community, i would share this project with you. The goal is to visualise the flow field around an airfoil at transsonic speed. The NACA 4 airfoil family was not designed for high subsonic speed. Thats the reason why this airfoil is interest testing. The Run3 was simulated with an inlet Speed of Ma 0.6 The fluid is modified that speed of sound is equal to 1m/s. the solver used for accurate transsonic simulation is rhoCentralFoam. my advice for accurate simulations with rhoCentralFoam. Co smaller 0.1 gradient calculation fourth if hexahedral is mesh is used Everybody who is interested, have a look on rho-, T-, U-Field. It is nice watching how the disturbances are traveling around the airfoil and forcing the boundary layer to separate.
