Definition
capability of a material entity to move by flow
Explanatory Notes
Flowability is assessed relative to a handling context and conditions (e.g., gravity discharge, pouring, conveying, pumping, geometry such as hoppers/orifices, temperature and humidity, consolidation history). In bioprocessing and pharmaceutical settings, the term is most commonly applied to powders and granular solids and evaluated using operational tests such as angle of repose, flow through an orifice, and indices derived from bulk and tapped density.
Examples
- the flowability of powdered cell culture medium during hopper discharge; the flowability of granular medium during transfer to a mixing vessel; the flowability of an excipient powder during tablet manufacturing; the flowability of chromatography resin slurry during transfer; the flowability of a dry powder after exposure to high humidity
