Filament stretching rheometer: inertia compensation revisited

Peter Szabo, Gareth H. McKinley

Research output: Contribution to journalJournal articleResearchpeer-review


The necessary inertia compensation used in the force balance for the filament stretching rheometer is derived for an arbitrary frame of reference. This enables the force balance to be used to extract correctly the extensional viscosity from measurements of the tensile force at either end of the elongating fluid column in any of the different experimental configurations that have been Introduced to date. The present analysis eliminates a restriction inherent in the work of Szabo.
