Simulation of the Critical Flashing Flow With the Transient 1D Two-Fluid Model

The paper presents results of the 1D computer code WAHA, developed for the water hammer simulations, applied for the simulation of the critical flashing flow in the “Super Moby Dick” convergent-divergent nozzle. The mathematical model of the code is briefly introduced with special emphasis on applied dispersed flow homogeneous-relaxation model of inter-phase heat and mass transfer. The results of the simulations of the critical flashing flow are compared to the experimental data.
