WebPowder flow is influenced by particle properties, such as size, shape, surface roughness and charge, and by external variables, for example, aeration or consolidation of the sample, or the ingress of moisture. The flow properties of powders are industrially critical but complex, and not yet amenable to mathematical modelling. WebMonitoring the rate of flow of material through an orifice has been proposed as a better measure of powder flowability. Of particular significance is the utility of monitoring flow continuously because pulsating flow patterns have been observed even for free flowing materials. Changes in flow rate as the container empties can also be observed.
