Performance of randomized Kelvin cell structures as catalytic substrates: Mass-transfer based analysis
Abstract
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, ε, 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 Lévêque equation (
Martin, 2002
) between mass and momentum transfer is evaluated and it is qualitatively in agreement with the results of
Incera Garrido et al. (2008)
on ceramic foams. Show more
