setAdvectionDiffusionTemperatureBoundary

[yx19971028]

Hello everone,
I want to use WallFunctionBoundary in the example called rayleighBenard3d in the thermal file.Can I use ‘setAdvectionDiffusionTemperatureBoundary’ as follows:
/// sets boundary
setWallFunctionBoundary<T,NSDESCRIPTOR>(NSlattice, superGeometry, 2, converter, wallFunctionParam);
setWallFunctionBoundary<T,NSDESCRIPTOR>(NSlattice, superGeometry, 3, converter, wallFunctionParam);

setAdvectionDiffusionTemperatureBoundary<T,TDESCRIPTOR>(ADlattice, Tomega, superGeometry, 2);
setAdvectionDiffusionTemperatureBoundary<T,TDESCRIPTOR>(ADlattice, Tomega, superGeometry, 3);
…
SmagorinskyBoussinesqCouplingGenerator3D<T,NSDESCRIPTOR>
coupling(0, converter.getLatticeLength(lx), 0, converter.getLatticeLength(ly),0, converter.getLatticeLength(lz),
boussinesqForcePrefactor, converter.getLatticeTemperature(Tcold), 1., dir, 0.87, NSbulkDynamics.getPreFactor());
NSlattice.addLatticeCoupling(coupling, ADlattice);

Your reply is much appreciated.

Thanks,

This might be possible but have probably not been tested yet.

Dear mathias,

Thank you for your reply.The simulation results I obtained are in good agreement with other papers.Is there any paper about ‘Advection Diffusion Temperature Boundary’?I want to learn about advection diffusion temperature boundary.

Yours sincerely.

Hello,

the implemented advection diffusion temperature boundaries are based on the scheme given in the book “The lattice boltzmann method” (Chapter 8.5) by Krüger et al. There are also further references to papers given.

Best,
Johanna
