| IT WORKED!

| Believe it or not, the picture shows MDM vapour flowing at supersonic speed! No condensation, this time… |
The pictures show preliminary result for virtual Schlieren visualization of a shock wave (bright line) and a rarefaction fan (dark region).
Top left picture shows the result obtained with a knife angle of 90 deg, a knife angle of 45 deg produces result shown in top right figure while in the bottom row are presented respectively a knife angle of 0 deg and an angle of 31 deg.
This latter value is the one corresponding to the shock-wave slope, so thath’s why the shock is badly highlighted!
Tthe flow field was computed using SU2!
We’re currently working on CUDA implementation, results will be available soon!
The flagship project of the CREA Laboratory, the ERC Consolidator Grant NSHOCK, officially started today!
The goal is to produce a nonclassical rarefaction shock wave in a steady nozzle flow of a mixture of siloxane fluids.
