The use of simulation tools has allowed companies to streamline their new product development processes reducing both cost and time-to-market. However, these virtual experimentation tools can be too complex and time consuming to be used by designers -that usually need a quick answer to compare and contrast different design solutions. This drawback is especially important when CFD (Computational Fluid Dynamics) is used to calculate the natural (non-forced) convection of a fluid, such as the oil inside an ONAN (Oil Natural Air Natural) distribution transformer or the air circulating in a transformer substation during the temperature-rise test. To address the situation described above, a customized simulation tool has been developed with the aim of reducing the computational cost that would require a model with the complete geometrical description. As a consequence both time-to-experiment and knowledge acquisition cost are reduced.
