Detailed Description

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

$\‍[ k_p = 1.5 (I |U|)^2 \‍]$

where

	=	kinetic energy at the patch
	=	turbulence intensity
	=	velocity field

In the event of reverse flow, a zero-gradient condition is applied.

Usage

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

Example of the boundary condition specification:

    <patchName>
    {
        type        turbulentIntensityKineticEnergyInlet;
        intensity   0.05;           // 5% turbulence
        value       uniform 1;      // placeholder
    }
