Revealing Actual Viscoelastic Relaxation Times in Capillary Breakup

Author(s): Nan Hu, Jonghyun Hwang, Tachin Ruangkriengsin, and Howard A. Stone We use experiments and theory to elucidate the size effect in capillary breakup rheometry, where prestretching in the viscocapillary stage causes the apparent relaxation time to be consistently smaller than the actual value. We propose a method accounting for both the experimental size and the finit… [Phys. Rev. Lett. 135, 048201] Published Wed Jul 23, 2025
