| Summary:
To achieve efficient liquid collection, a surface must regulate incoming
liquid accumulation with outgoing liquid transport. Often, this can be proposed
to be achieved by functionalizing surfaces with non-wetting characteristics.
Yet, there remain fundamental, practical limits to which non-wetting surfaces
can effectively be employed. We instead utilize filmwise wetting to achieve
liquid regulation via a Laplace pressure gradient induced by solid surface
curvature. The key parameters affecting this capillary flow are then
introduced, namely solid properties like scale and curvature and liquid
properties like surface tension and density. The liquid regulation mechanism
can then be employed in condensation and aerosol processes to generate enhanced
flow, while the solid geometry needed to create this capillary flow itself is
capable of affecting and enhancing liquid generation. Ultimately, the surface
design framework can be customized to each unique application to optimize
processes in HVAC, industrial steam generation, chemical depositions, and
atmospheric water harvesting.
