Similarly, in batch settling experiments, the hindered settling function R(ϕ) characterises the apparent sedimentation velocity of the suspension and thus the interphase drag

that flocculated particulate suspensions are ratchet poro-elastic rather than plastic under compressive stress, the compressive yield stress Py(ϕ) can be related to the bulk elastic modulus 𝐾(𝜙) as 𝑃!(𝜙)=∫𝐾(𝜙) 𝑑 𝑙𝑛 𝜙, so characterisatio · 2013
