GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.
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.
