Abstract:
In the present reply we show that the comments casting doubts on the results of our recent paper [M. De Corato et al., Phys. Rev. E 92, 053008 (2015)PLEEE81539-375510.1103/PhysRevE.92.053008] are based on a misinterpretation of the second-order fluid constitutive equation. Nevertheless, we show that, by considering alternative constitutive equations for the viscoelastic stress, we recover, to first-order in the Deborah number, the same results already obtained by De Corato et al. [Phys. Rev. E 92, 053008 (2015)PLEEE81539-375510.1103/PhysRevE.92.053008], thus dissipating any possible doubt about their validity.

The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
