本文在润滑理论的框架下，推导了液滴在厚多孔基底上的铺展和吸附模型。在多孔材料的饱和部分中的流动由达西定律支配，假设将饱和区域与非饱和区域分离的不连续润湿前缘。数值结果的液滴的扩散和吸附在其依赖于轴对称和二维配置的材料和工艺参数。(C)2004 Elsevier Ltd.保留所有权利。
In this paper, a model for spreading and sorption of a droplet on a thick porous substrate is derived in the frame of lubrication theory. Flow in the saturated part of the porous material is governed by Darcy's law, assuming a discontinuous wetting front separating the saturated from the unsaturated regions. Numerical results are presented for spreading and sorption of droplets in their dependence on the material and process parameters for axisymmetric and two-dimensional configurations.
