The fvDOM radiation model of OpenFOAM is not
applicable to axisymmetric geometries, resulting
in:
Increased computational costs,
Complicated mesh generation,
Reduced numerical stability.
Solution
Implement and verify the axisymmetric fvDOM
boundary condition elaborated in:
Kumar, P., & Eswaran, V. (2013). A methodology to
solve 2D and axisymmetric radiative transfer
problems using a general 3D solver. Journal of
heat transfer, 135(12).
Verification
Based on:
Cai, J., & Modest, M. F. (2016). Specular reflective boundary conditions for Discrete Ordinate
Methods in Periodic or Symmetric Geometries. In Journal of Physics: Conference Series (Vol. 676, No. 1, p. 012002). IOP Publishing.
Risks
No change in existing input/output.
The predictions of the condition for the radial heat flux distribution on walls need to be improved.
