WebFlowability of a bulk solid is characterized mainly by its unconfined yield strength (σ c) as a function of the consolidation stress (σ 1) and the storage period, t.Usually, the ratio ff c of consolidation stress (σ 1) to unconfined yield strength (σ c) is used to characterize flowability numerically by flow index ff c.The larger ff c is, i.e., the smaller the ratio of … WebIncompressible flow. In fluid mechanics or more generally continuum mechanics, incompressible flow ( isochoric flow) refers to a flow in which the material density is constant within a fluid parcel —an infinitesimal volume that moves with the flow velocity.
