Abstract
We describe a study conducted to examine the influence of turbulence on the flow and heat transfer in graphitic foams. In this study, a Large Eddy Simulation (LES) model was used to characterize turbulence in the momentum and energy balances, and calculations were done to produce transient results of the velocity and temperature fields inside the spherical pores of the foam. The LES simulations enable excellent insight into the pore-level heat transfer mechanisms for the spherical void shape, and show that the heat transfer increases by a factor of 4.7 for an order of magnitude increase in the Reynolds number.
