    Numerical simulations of NICFD flows with SU2 vs experiments!

    First-ever assessment of a CFD code against experimental data for non-ideal compressible-fluid flows of interests for ORC applications is ongoing. Grid adaptation helps capturing shock waves.

    Laser Doppler Velocimetry @TROVA

    The first measurements using Laser Doppler Velocimetry are currently being carried out @TROVA. These are the first-ever velocity measurements within a non-ideal compressible-fluid flows in the close proximity of the liquid-vapour saturation curve. The flow seeding required the design and construction of a the pressurised seeding apparatus shown in the picture.

    IT WORKED! 

    Believe it or not, the picture shows MDM vapour flowing at supersonic speed! No condensation, this time…
