The aim of this contribution is to present an empirical model taking into account ageing of highly concentrated emulsions. This model enables smooth passage from modelling of viscoelastic fluid (shear-thinning behaviour) corresponding to a "fresh" material to a description of viscoplastic fluid (viscoplastic behaviour) corresponding to an "aged" material including yield stress modelling
Cílem tohoto příspěvku je presentovat empirický model zohledňující stárnutí emulsí, tj. presentace modelu spojitě přecházejícího z popisu 'shear-thinning' kapalin na popis vazkoplastických materiálů s nenulovou mezí kluzu
