Transient elongational flow, created by forcing a polymer solution across a narrow contraction, is characterized by a high strain rate of limited duration. Due to an inherent short residence time, this type of flow generally is considered as being less efficient in extending isolated flexible molecu
A systematic framework introduced recently to obtain parameter-free predictions of material properties of dilute polymer solutions in extensional ows is reviewed. The essential constraint of ensuring that the model polymer molecule has a ΓΏnite length is met by using a bead-spring chain model with ΓΏn
