Detailed Description

This boundary condition provides a turbulent kinematic viscosity condition when using wall functions for rough walls, based on velocity, using Spalding's law to give a continuous nut profile to the wall (y+ = 0)

$y^+ = u^+ + \frac{1}{E} \left[exp(\kappa u^+) - 1 - \kappa u^+\, - 0.5 (\kappa u^+)^2 - \frac{1}{6} (\kappa u^+)^3\right]$

where

	=	non-dimensional position
	=	non-dimensional velocity
$\kappa$	=	Von Karman constant

Usage

Example of the boundary condition specification:

<patchName>
{
    type            nutUSpaldingWallFunction;
}
