Spreading and sorption of droplets on layered porous substrates.

摘要: In this paper spreading and sorption of a droplet on an anisotropic, layered porous substrate are investigated numerically. Flow in the saturated part material is governed by Darcy's law, assuming sharp wetting front separating regions from dry regions. Numerical results presented for droplets their dependence process parameters axisymmetric configurations. Limiting cases into infinitely thick very thin layers considered. For analytical model substrates fed infinite reservoir correction term taking account flow resistance inlet region derived consistence modified with numerical experimental shown. two-layer substrates, influence layer permeabilities kinetics presented.
