How do you simulate non-condensable gases in conjunction with cavitation?
There are three options to take non-condensable gases (NCGS) into account. Options 1 and 2 are highly recommended because of their robustness.
- Zwart-Gerber or Schnerr-Sauer cavitation models and three-phase system: liquid + vapor + compressible NCGS
- Zwart-Gerber or Schnerr-Sauer cavitation models and two-phase system: liquid + compressible mixture of vapor and NCGS
- The Singhal cavitation model, which can be activated by TUI. In this model, the volume fraction in post-processing is the sum of vapor and NCGS. To see the vapor only, use the following command: (rpsetvar 'cvt/total-gas-vof? #f)
