Nanoengineered Surfaces: Transport Phenomena and Energy Applications -- Nanoengineered surfaces offer new possibilities to manipulate fluidic and thermal transport processes for lab-on-a-chip, thermal management, and energy conversion systems. In this talk, fundamental studies of droplet and bubble behavior on nanoengineered surfaces, and the effect of these fluid-structure interactions on boiling and condensation heat transfer will be discussed. Critical heat fluxes of ≈250 W/cm2 in pool boiling and ≈100% higher condensation heat transfer coefficients compared to state-of-the-art dropwise surfaces were achieved. These studies provide important insights into the complex physical processes underlying fluid-nanostructure interactions and promise the development of more efficient energy systems.
