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