Transient filament stretching rheometer I: force balance analysis

Research output: Contribution to journalJournal articleResearchpeer-review


The filament stretching device which is used increasingly as an apparatus for measuring extensional properties of polymeric liquids isanalysed. A force balance that includes the effects of inertia and surface tension is derived.The force balance may be used to correct for the effects of inertia and surface tension, provided online measurements of the filament surface shape are available. In addition the question of initial asymmetry due to gravity is addressed.
