Do the Schnerr-Sauer and Zwart-Gerber-Belamri cavitation models have built-in correction of the saturated vapor pressure in consideration of the pressure fluctuations due to turbulence?

      Singhal-et-al in R6.3 could not account for variations in saturated vapor pressure due to turbulence. Two cavitation models have been added in R12: •Schnerr-Sauer (default) •Zwart-Gerber-Belamri This correction in R13 is possible by the following input command: (rpsetvar ‘mp/pvap/turbulence-factor? #t) Note: Please note that it is not taken into account even in R13 by default. Information on the cavitation models can be found in section 16.7.4 of the Fluent 12.0 theory Guide or section 17.7.4 for Fluent 13.
