Performance of randomized Kelvin cell structures as catalytic substrates: Mass-transfer based analysis
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.
