THERMAL MODELING OF POWER TRANSFORMER RADIATORS USING A POROUS MEDIUM BASED CFD APPROACH

摘要：

In power transformer cooling applications, the heat transfer in large fan-cooled radiator batteries and their immediate surroundings can be successfully studied using a CFD model in which the mixed convection based oil and air flows and the heat transfer between these media in the radiators is modelled using an anisotropic porous medium approach and the area surrounding the radiators using a standard turbulent heat transfer model. The resulting model appears fast enough to allow a large number of realistic simulations to be run to study the effect of radiator design parameters like fan position, fan size and oil flow rate on the cooling capacity of the radiators. As an example the analysis of the effect of fan size on radiator cooling capacity is shown.
