About Pressure-Dependent Calculations
Defining the Process Simulation
It is possible to apply variable pressure during process metallurgical calculations, which is relevant in various processes such as Vacuum Oxygen Decarburization (VOD) or Ruhrstahl-Heraeus (RH).
The implementation includes all relevant features for a realistic modeling of the pressure-dependency:
- the set pressure at a time-step is valid for all bulk and reaction zones of the system
- the exhaust gas zone has always atmospheric pressure
- the added material (only relevant for gas) has initially always atmospheric pressure
- the material transferred to and from the zones (i.e. the added material and the exhaust gas from the zones) is undergoing an adiabatic expansion / compression because it is moved between different pressures
Generally there is no effect of pressure change on anything else than gas (due to physics and the implementation of the database).
