ENH: specularRadiation: add axisymmetric fvDOM boundary condition

Kutalmış Berçin requested to merge feature-axisymmetric-fvdom-bc into develop


The fvDOM radiation model of OpenFOAM is not applicable to axisymmetric geometries, resulting in:

  • Increased computational costs,
  • Complicated mesh generation,
  • Reduced numerical stability.


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).


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.


  • No change in existing input/output.
  • The predictions of the condition for the radial heat flux distribution on walls need to be improved.
