Скачать или смотреть Gπ Engineering : FEM/CFD Results of Trefoil Cables in Ducts in a Trough 2D: Full vs 1/2 Symm Models

Giglio Power Infrastructure Engineering

In this video (less than 5 min) I use FEM/CFD with COMSOL Multiphysics to model (full and 1/2 symmetry) three trefoil cables (400kV) in ducts inside a trough buried 2m below the surface and compute the steady state ampacity. These ampacity values were used in a temperature run towards steady state to ensure the maximum conductor temperature limit (90 C) is not exceeded. The half symmetry model results were obtained in about 2/3 the simulation time of the full model and the results are practically the same.
