• Select the BCs tab

Creating Boundary Conditions:
In this case, an inflow is at X min, an outflow at X max, axis of symmetry at Y min, wall
at Y max, and symmetry boundary conditions at Z min and Z max. Follow the step-by-step
instructions below to create the inflow boundary condition and define its properties.

• From the Inflow BC available, click to set the boundary condition properties

• Fill in the inflow properties - Tab: Basic

– Inflow Data Source: From BC
– Inflow Type: Velocity based
– Inflow profile: Turbulent

– Inflow Static Temperature: 345.8 K
– Inflow Velocity components: u: 1.0 v: 0.0 w: 0.0

• Fill in the inflow properties - Tab: Turbulence (RANS)
– Turbulent Intensity: 0.1

– Mu t/Mu: 100

• Fill in the inflow properties - Tab: N-Phases Algebraic Slip Model
– Inflow Volume Fraction of Phase 1: 0.003
– Inflow Volume Fraction of Phase 2: 0.997
