Spatiotemporal instability and topological bifurcations of a weakly elastic film flowing down a vertical fibre

This paper investigates the temporal, spatiotemporal and nonlinear instability of a weakly viscoelastic liquid film flowing down a vertical cylindrical fibre. The fluid is described by the Walters’ liquid B model, and the analysis combines long-wave asymptotic modelling, a long-w...
