Limitation of Proposed Mathematical Models for the Porosity Estimation of Nonspherical Particle Mixtures

The porosity of nonspherical particles may technically be estimated by a mathematical model for estimating the porosity of spherical particles. The applicability of the simplified packing model and the linear-mixture packing model recently proposed in the literature is investigated. It is found that, in spite of the reported successful application to some situations, the two models cannot generally be used to estimate the porosity of nonspherical particle mixtures.
