Resumo(s)
• In confined foams there exist wall Plateau borders (PBs), or menisci, where the films meet the confining substrates.
• What is the shape of a PB of a given size on a surface of a given wettability (i.e., contact angle θc)? Can that surface support a foam?
• This is important for firefighting foams, containers for foamy foodstuffs, etc
• We solve the Young-Laplace equation with gravity for a planar film spanning
a gap between two horizontal, flat substrates, to predict the shape of the PBs.
• Validate results by comparing with Surface Evolver and experimental data
