Abstract

Three-dimensional numerical simulations are run on a cylindrical electrical transformer that is generating heat in order to study the resulting natural convection that is driven by density variation. The transformer generates a constant heat flux and is incased in a sleeve with radial fins. At first, the sleeve is analyzed without fins and compared to an analytical solution in order to validate the numerical simulations. Next, fins are added to the sleeve in order to maximize the heat transfer from the transformer. Heat transfer from the sleeve per number of fins is to be determined. Small pins are then added to the channels between the fins in order to perturb the flow and thermal boundary layer with the goal of increasing heat transfer. Results show that adding the pins to both the base and fins increases heat transfer but adding pins to the base alone does not guarantee an increase in heat transfer.
