Detailed Description

Kunz cavitation model.

Slightly modified so that the condensation term is switched off when the pressure is less than the saturation vapour pressure. This change allows the condensation term to be formulated as a coefficient multiplying (p - p_sat) so that it can be included as an implicit term in the pressure equation.
