Detailed Description

This boundary condition provides a wall constraint on the kinematic turbulent thermal conductivity (i.e. alphat) for atmospheric boundary layer modelling. It assumes a logarithmic distribution of the potential temperature within the first cell.

Required fields:

  alphat    | Kinematic turbulent thermal conductivity    [m2/s]

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type            atmAlphatkWallFunction;
    Pr              <Function1<scalar>>;
    Prt             <PatchFunction1<scalar>>;
    z0              <PatchFunction1<scalar>>;

    // Optional entries
    Cmu             <scalar>;
    kappa           <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: atmAlphatkWallFunction	word	yes	-
`Pr`	Molecular Prandtl number	Function1<scalar>	yes	-
`Prt`	Turbulent Prandtl number	PatchFunction1<scalar>	yes	-
`z0`	Surface roughness length [m]	PatchFunction1<scalar>	yes	-
`Cmu`	Empirical model constant	scalar	no	0.09
`kappa`	von Kármán constant	scalar	no	0.41
