From: Penetration and ligament formation of viscoelastic droplets impacting on the superhydrophobic mesh
The ligament dynamics. (a) Tiem evolution of the ligament length for meshes with pore sizes S = 357 μm at We = 66 and 0.5 g/L PEO concentration. The solid green line shows the fitted curve by the spring-damper equation of motion. (b) The maximum ligament length versus the Weber number for meshes with pore sizes S = 357 μm and different PEO concentrations. (c) The spring constant and the (d) damper coefficient were extracted from the spring-dashpot modeling.
