Detailed Description

This source condition provides a turbulent kinetic energy based on user-supplied turbulence intensity, defined as a fraction of the mean velocity:

\[ k = 1.5 (I |U|)^2 \]

where

$ k $ = kinetic energy values
$ I $ = turbulence intensity
$ U $ = velocity field

In the case of a sink, the current cell values are used instead.

Usage
Property Description Required Default value
intensity fraction of mean field [0-1] yes
U velocity field name no U

Example of the boundary condition specification: 

    <sourceName>
    {
        type        turbulentIntensityKineticEnergyInlet;
        intensity   0.05;           // 5% turbulence
    }
