Effects of viscoelasticity on drop impact and spreading on a solid surface

  author={Daulet Izbassarov and Metin Muradoglu},
The effects of viscoelasticity on drop impact and spreading on a flat solid surface are studied computationally using a finite-difference–front-tracking method. The finitely extensible nonlinear elastic–Chilcott-Rallison model is used to account for the fluid viscoelasticity. It is found that viscoelasticity favors advancement of contact line during the spreading phase, leading to a slight increase in the maximum spreading, in agreement with experimental observations [Huh, Jung, Seo, and Lee… CONTINUE READING
