Patent Pending
IntraFlow™ Vaporizing Regulator
• CFD modeling of the
vaporizer indicates that
room temp water
vaporizes at around
80% through the heat
exchanger
Number of Tetrahedral Elements = .42 million
Pressure Inlet: 25 psi
Pressure outlet : 5 psi
Temperature input to aluminum block: 190 oC
All other external walls are considered as adiabatic walls
Fluid: Water
Solver:
Segregated 3D steady solver with SIMPLE pressurevelocity coupling with standard k-e turbulence model.
