Open cell foams are attractive materials for various industrial applications, but building accurate universal correlations is challenging due to their great geometrical complexity. Momentum and mass transfer of a randomly packed Kelvin cell structures are numerically investigated. Porosity, e, Kelvin cell size, PPI, and inflow velocity, u, are systematically varied for a total of 120 simulations. Correlations for geometrical and transfer properties are discussed. The analogy based on the generalized Leveque equation (Marlin, 2002) between mass and momentum transfer is evaluated and a is qualitatively in agreement with the results of Incera Garrido et al. (2008) on ceramic foams. (C) 2014 Elsevier Ltd. All rights reserved.
