Uploaded by mariostorti on Apr 7, 2009
The fluid flow and heat transfer in the fluid, core, and wire windings have been computed with the OpenSource Finite Element Code PETSc-FEM http://www.cimec.org.ar/petscfem . 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 http://www.cimec.org.ar/ojs/index.php/mc/article/view/763 (in Spanish).
