From: Penetration and ligament formation of viscoelastic droplets impacting on the superhydrophobic mesh
Diagram of the penetration during the reoiling in terms of dynamic pressure induced by jet (\({P}_{Dj}\sim {\rho }^{3/2}{R}_{j}^{1/2}{\gamma }^{-1/2}{v}_{j}^{3}\)) versus the capillary pressure \(4\gamma /S \text{cos}({\theta }_{a})\) for (a) Water droplet, (b) 0.5Â g/L, PEO aqueous droplet. The symbols represent different spray phenomena, the solid symbols show the recoil penetration, and the cross symbol (x), shows no recoil penetration. The dashed line shows \({P}_{Dj}\)=\({P}_{c}\) and the dashed-dotted line shows \({P}_{Dj}\)=\({c}_{0}{P}_{c}\) when c0 is the correction coefficient.
