Coupled thermal and aqueous FEM ciphering in an electrical transformer

!: Coupled thermal and aqueous FEM ciphering in an electrical transformer

The fluid flow and heat transfer in the fluid, core, and wire windings have been computed with the OpenSource Finite Element Code PETSc-FEM www.cimec.org.ar . The FEM mesh has been highly refined in the solid-fluid interface due to the high Prandtl number of the oil. The results shown correspond to the warm-up essay on a distribution transformer of 13.2/0.4 kV, 315kvA. More info in the following article www.cimec.org.ar (in Spanish).
