Nanostructure Surface Modifications for Enhanced Phase Change Heat Transfer

Description :  

The objective of the investigator of this research is to enhance phase change heat transfer in working fluids, which play an important role in space exploration, power production, and refrigeration systems. The investigator proposes to explore various orientations and conditions in horizontal heat transfer surfaces using aligned nanowire arrays operating as scalable surface modifications in selective areas of thermal test components. It is proposed that the nanowire arrays may provide significant, long-term phase change heat transfer enhancement. Specifically, the arrays may provide advantageous hydrodynamic and nucleation conditions while simultaneously allowing for smaller, lighter, and more compact heat exchangers with enhanced reliability in aerospace applications.
