CMC solution filament thinning behaviour showing complex behaviour. ( a ) 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. ( b ) Filament break-up times increased linearly with initial gap size. Seymour yielded consistently shorter break-up times than the Trimaster.
