Figure 3. Relaxation of the central height of the wetting ridge after drop deposition.

The curves show the approach to equilibrium height, h_∞−h at x=0, for two rheologies: (a) power-law rheology (equation (1) with n=1/2) and (b) standard linear model, β=300 (equation (11), see inset). The dimensionless substrate thickness for these plots was γ_s/(Gh₀)=0.5.
