CMC solution filament thinning behaviour showing complex behaviour. (
) Seymour testing, alongside best fit lines for the Newtonian and Giesekus models. The data are plotted against dimensionless time, t/t
F. Laboratory and field measurements largely agree. (
) Filament break-up times increased linearly with initial gap size. Seymour yielded consistently shorter break-up times than the Trimaster.
