Parallel CFD Analysis of Conjugate Heat Transfer in a Dry Type Transformer

摘要

In this paper we present the conjugate heat transfer analysis in a 167 kVA dry type transformer using the parallel version of the CFD code Fluent 6.0. The RNG κ-ε model is proposed to compute the turbulent aspect of the convective airflow inside the transformer metal tank, for ANAN (Air Natural Air Natural) cooling conditions. An experimental approach was used to assess Joule losses in the low/high voltage windings and Eddy currents losses in the magnetic core. The resulting mathematical model was solved using 14 compute nodes on a distributed machine.
