Detailed Description

This boundary condition provides a turbulence dissipation, $\epsilon$ (epsilon) inlet condition based on a specified mixing length. The patch values are calculated using:

$\epsilon_p = \frac{C_{\mu}^{0.75} k^{1.5}}{L}$

where

$\epsilon_p$	=	patch epsilon values
$C_{\mu}$	=	Model coefficient, set to 0.09
	=	turbulence kinetic energy
	=	length scale

Usage

Property	Description	Required	Default value
`mixingLength`	Length scale [m]	yes
`phi`	flux field name	no	phi
`k`	turbulence kinetic energy field name	no	k

Example of the boundary condition specification:

    <patchName>
    {
        type            turbulentMixingLengthDissipationRateInlet;
        mixingLength    0.005;
        value           uniform 200;   // placeholder
    }

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