Flow and heat dissipation analysis in transformer substation with minimal ventilation using CFD

This paper aims to investigate the flow and heat dissipation of a transformer located in substation building with minimal ventilation system. The study is carried out using CFD, which model the flow and conjugate heat transfer in step-up transformer and its surrounding air. Transformer model is gene...
