Profiting from their slippery nature, lubricant-infused porous surfaces endow with droplets excellent mobility and consequently promise remarkable heat transfer improvement for dropwise condensation. To be a four-phase wetting system, the droplet wettability configurations and the corresponding dynamic characteristics on lubricant-infused porous surfaces are closely related to many factors, such as multiple interfacial interactions, surface features, and lubricant thickness, which keeps a long-standing challenge to promulgate the underlying physics. In this work, thermodynamically theoretical analysis and three-dimensional molecular dynamics simulations with the coarse-grained water and hexane models are carried out to explore droplet wettability and mobility on lubricant-infused porous surfaces.

- - The study uses a multicomponent multiphase thermal lattice Boltzmann model to analyze how droplets condense in the presence of non-condensable gases, focusing on how interactions among droplets create asymmetric condensation patterns.
- - Findings show that isolated droplet growth exhibits symmetric characteristics, but when droplets grow in patterns, their competition for vapor creates overlapping concentration profiles, leading to asymmetric temperature and flow patterns.
- - Asymmetric condensation not only alters the droplet's surface conditions but can also induce droplet motion, with the degree of this interaction heavily depending on droplet size and distance from one another; the growth rate follows a power law influenced by these interactions.
