30Description
31 Kunz cavitation model slightly modified so that the condensation term
32 is switched off when the pressure is less than the saturation vapour
33 pressure. This change allows the condensation term to be formulated as
34 a coefficient multiplying (p - p_sat) so that it can be included as an
35 implicit term in the pressure equation.
