Abstract
The predictions of the Marrucci and Ianniruberto model (2003) have been studied in various rheometric flows as well as a planar elongation flow using the ‘optical elongational rheometer’ technique proposed by Schuberth and Münstedt (Rheol Acta 47:111–119, 2008). This combination of techniques extended the range of pertinence of the model to high-extensional rates. Relevance of the identified parameters with respect to tube theory was then discussed.
