Detailed Description

This boundary condition provides a kinematic turbulent thermal conductivity for using wall functions, using the Jayatilleke 'P' function.

Usage
Example of the boundary condition specification: 
<patchName>
{
    // Mandatory entries
    type            alphatJayatillekeWallFunction;

    // Optional entries
    Prt             <scalar>;
    kappa           <scalar>;
    E               <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property Description Type Reqd Deflt
type Type name: alphatJayatillekeWallFunction word yes -
Prt Turbulent Prandtl number scalar no 0.85
kappa von Karman constant scalar no 0.41
E Wall roughness parameter scalar no 9.8

The inherited entries are elaborated in:

Note
  • The units of kinematic turbulent thermal conductivity are [m2/s].
