Natural break-up and satellite formation regimes of surfactant-laden liquid threads

27 Nov 2019 Martínez-Calvo A. Rivero-Rodríguez J. Scheid B. Sevilla A.

We report a numerical analysis of the unforced break-up of free cylindrical threads of viscous Newtonian liquid whose interface is coated with insoluble surfactants, focusing on the formation of satellite droplets. The initial conditions are harmonic disturbances of the cylindrical shape with a small amplitude $\epsilon$, and whose wavelength is the most unstable one deduced from linear stability theory...
