Define Initial Turbulence by Specifying Turbulent Viscosity
-
From the
Initial Conditions section of the
action bar,
click
Initial Turbulence
.
- Optional: Enter a descriptive Name.
-
Select the geometry supports in the model.
An initial turbulence must be applied to one or more fluid regions. You can click the
glyph in the model to select the fluid domain.
- From the Turbulence specification options, select Turbulent viscosity.
-
Specify the
Kinematic eddy viscosity.
The kinematic eddy viscosity, ˜v, must be a nonzero value and should be roughly three to five times the kinematic viscosity. The kinematic viscosity is the ratio of the fluid viscosity and density (ν=η/ρ)
- Click OK.
