An additional air inflow boundary condition to be assigned to the Z max surface will be created:

• Click

• Rename newbc0 to air inflow
• Select Inflow in the drop-down box of the Type column

• Click

• Fill in the inflow properties as follows:

– Inflow Data Source: From BC
– Inflow Type: Velocity based
– Inflow Profile: Laminar
– Inflow Temperature: 300

– Inflow Velocity components: u: 0.0 v: 0.0 w: 0.0
• Select the N-Phases Algebraic Slip Model tab on the left-hand side of the inflow prop-
erties window, then set:

– Inflow Volume Fraction of phase 2: 1.0
– Phase 1 Velocity [m/s]: u: 0.0, v: 0.0, w: -9.28
– Phase 2 Velocity [m/s]: u: 0.0, v: 0.0, w: -9.28
– Phase 3 Velocity [m/s]: u: 0.0, v: 0.0, w: -9.28

• Click to save the settings and close the window
