Landau-levich-derjaguin law
TīmeklisCORE – Aggregating the world’s open access research papers Tīmeklis2016. gada 25. nov. · We demonstrate that the generalized Landau–Levich equation has a branch of stable steady state solutions and a branch of unstable solutions. The branches meet at a saddle-node bifurcation point corresponding to the threshold value of the SAW intensity.

Tīmeklis2016. gada 13. dec. · We observe two types of entrainment. (i) The thickness of the air gap is found to increase with the plate speed, which is interpreted in the Landau-Levich-Derjaguin frame: Air is dynamically dragged along the surface and its thickness results from a balance between capillary and viscous effects. TīmeklisWe further demonstrate that for a moving droplet, the film thickness follows the Landau-Levich-Derjaguin law. The droplet is therefore oleoplaning - akin to tyres hydroplaning on a wet road - with minimal dissipative force and no contact line pinning. The techniques and insights presented in this study will inform future work on the ...
