Jan 01, 2016 · By contrast, in funnel flow, an active flow channel forms above the outlet, but stagnant material remains (called ratholes) at the periphery of the vessel. Funnel flow can cause erratic flow, exacerbate segregation, reduce the live capacity of a vessel, allow particle degradation (leading to caking and spoilage) in stagnant regions.

Funnel-flow discharge results in material stagnation along the hopper walls. Many undesirable flow effects can occur with a funnel-flow pattern. p Figure 5. Mass-flow discharge occurs when material flow is achieved against the sloping hopper walls. A mass-flow pattern prevents ratholing, allows first-in/first-out flow, and minimizes segregation.
