- •
Water vapor condensing on aluminum plate in presence of non-condensable gases.
- •
Wettability-patterned tracks on condensing surface rapidly remove condensate.
- •
Sample surface preparation is facile, scalable, does not add to the metal surface.
- •
Optimal design by changing the fractional areas of dropwise/filmwise condensation.
- •
Heat transfer improvement over 30% compared to dropwise condensation surface.
