To solve hydraulic (isothermal) cavitation problems, a new hybrid method is introduced.
Hydraulic (isothermal) cavitation occurs in liquid flows when the pressure falls below a critical value. As a result a supersonic flow frequently occurs in two-phase cavitation zones. To solve such problems, the hybrid solver applies both incompressible (liquid area) and compressible solvers (two-phase area).
The hybrid method automatically turns to appropriate approach depending on flow regime. It only applies to isothermal cavitation.
