Critical wetting angle for spontaneous liquid infiltration into orderly packed fibres or spheres
- 113 Downloads
The static mechanics requirement for liquids to infiltrate spontaneously into orderly packed monosized spheres or fibres is studied. It is found that a wetting angle much lower than 90 ° is required to achieve spontaneous infiltration, and this wetting angle also varies considerably with respect to the infiltration direction, the arrangement of the fibres or spheres, and the packing density.
