ENH: specularRadiation: add axisymmetric fvDOM boundary condition

Problem

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.
