Inlet
Use the Inlet node to define an edge or point where fluid enters the gap.
Inlet Settings
Select an Inlet condition — Zero pressure (the default), Pressure, or Normal inflow velocity. The option Starvation is also available when Liquid with cavitation is selected in the Physical Model section.
•
For Zero pressure pfilm = 0 applies on the boundary, edge, or point.
•
For Pressure enter the Pressure pfilm0 (SI unit: Pa) to impose pfilm = pfilm0 on the boundary, edge, or point. The default is 0 Pa. If the reference pressure pref = 0 in the Reference Pressure section, then pfilm0 represents the absolute pressure, otherwise pfilm0 sets the relative pressure with respect to pref.
•
For Normal inflow velocity enter a Normal inflow velocity U0. The default is 0 m/s.
•
For Starvation enter a value for the Fluid fraction θ0. The default is 0.6 (dimensionless).
