Natural convection has attracted a great deal of attention from researchers because of its presence both in nature and engineering applications. In nature, convection cells formed from air raising above sunlight-warmed land or water are a major feature of all weather systems. Convection is also seen in the rising plume of hot air from fire, plate tectonics, oceanic currents (thermohaline circulation) and sea-wind formation (where upward convection is also modified by Coriolis forces).
As the temperature rises above the permitted level, transformators may be in danger. Different types of transformators have different cooling options by considering their volumes. Convection heat transfer in a transformator can be carried out in different ways using different fluids. One of the most important of these methods is the natural cooling with air and oil.
In this system, the oil inside the transformator flows naturally to allow heat transfer. The air in contact with the radiator body cools the radiator of the transformator. From the perspective view of mechanical fluid engineering, this issue is a free convection heat transfer problem.
In this analysis, we tried to simulate and analyze the 3D flow of free convection heat transfer in a transformator using Ansys Fluent software.
