Detailed Description

This boundary condition provides a wall constraint on the turbulent viscosity (i.e. nut) based on velocity (i.e. U), for low- and high-Reynolds number applications.

As input, the user specifies a look-up table of u+ as a function of near-wall Reynolds number.

The table should be located in the $FOAM_CASE/constant directory.

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type            nutTabulatedWallFunction;
    uPlusTable      myUPlusTable;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: nutUTabulatedWallFunction	word	yes	-
`uPlusTable`	u+ as a function of Re table name	word	yes	-

The inherited entries are elaborated in:

Note

The tables are not registered since the same table object may be used for more than one patch.
