Description🔗
The compressible::alphatPhaseChangeJayatillekeWallFunction
is a boundary condition that provides
a thermal wall function for turbulent thermal diffusivity (usually alphat
)
based on the Jayatilleke model for the Eulerian multiphase solvers.
Usage🔗
The condition requires entries in both the boundary and field files.
