Summary:
Iowa State University researchers have demonstrated enhanced heat transfer efficiency for phase change operations.

Development Stage:
Description:
Iowa State University researchers have produced biphilic copper surfaces by chemical modification of the surface. Using this method, spatially controlled hydrophilic and hydrophobic areas exist proximately on a single surface; the hydrophilic areas promote contact between the liquid phase and the heat transfer surface, leading to an enhancement in the critical heat flux, while the hydrophobic areas increase nucleation sites, resulting in an enhanced heat transfer coefficient. Discrete patterns can be created to further enhance the efficiency of boiling and promote energy efficiency.

Advantage:
• Micropatterning of copper produces biphillic surface to both promote nucleation and enhance the contact of liquid water to the surface
• Coating-free method provides long-term surface treatment
Application:
Heat exchangers, boilers
