Vladimír Goga – Juraj Paulech – Michal Váry

   This paper describes calculation of cooling process of electrical Cu conductor with PVC insulation. Three types of solutions were performed.Analytical solution considers free convection and radiation effect of heat transfer. Numerical solution was performed by finite element method (FEM) using software ANSYS Workbench and fluid flow solution was performed by computational fluid dynamics (CFD) analysis in software ANSYS CFX. Results from all types of solutions were compared with results of the experimental measurement.

Keywords: electro-thermal analysis, CFD analysis, cooling of insulated conductor, measurement, PVC
