Abstract
Theory and numerical simulations of the thinning of liquid threads at high superficial concentration of surfactants suggest the existence of an asymptotic regime where surface tension balances surface viscous stresses, leading to an exponential thinning with an e-fold time F(Theta)(3mus + kappas)/sigma, where mus and kappas are the surface shear and dilatational viscosity coefficients, sigma is the interfacial tension, Theta = kappas/mus, and F(Theta) is a universal function. The potential use of this phenomenon to measure the surface viscosity coefficients is discussed.
