Heat-transfer enhancement and evaporation mechanisms on roughness-controlled wettability-contrast surfaces

Puntos clave

• Enhanced heat-transfer was observed due to increased surface roughness, leading to improved phase change dynamics.
• Key evidence showed that the surfaces with wettability contrast achieved a 25% increase in heat-transfer efficiency during tests.
• Analysis using thermal conductivity measurements confirmed that roughness plays a crucial role in evaporation rates across diverse surfaces.
• These findings support the development of advanced cooling technologies, potentially impacting energy-efficient systems.
