Micro/nanoengineered surfaces offer new avenues to manipulate thermal and fluidic transport for a variety of engineering applications ranging from microfluidics to energy conversion systems. In particular, micro/nanostructured surfaces have been demonstrated to enhance phase change heat transfer by manipulating bubble/droplet/particle-surface interaction. In this talk, I will discuss the role of fluid-structure interactions on thin-film evaporation and condensation heat transfer. In thin-film evaporation, we explained the role of micro/nanostructuring in manipulating fluidic and thermal transport with experiments and modeling. Accordingly, we demonstrated the promising potential of thin-film evaporation as a thermal management solution for power-dense applications. In condensation, we facilitated droplet shedding by using slippery liquid infused porous surfaces (SLIPS) to improve the overall heat transfer coefficient. These studies provide key insights into the complex physical processes underlying fluid-structure interactions for phase change heat transfer in addition to offering a path to achieving increased efficiency in next generation energy systems.
Solomon Adera earned his B.S. degree from the Georgia Institute of Technology in 2009 and S.M. and Ph.D. from the Massachusetts Institute of Technology in 2012 and 2016, respectively all in Mechanical Engineering. Currently, he is a Postdoctoral Associate in the School of Engineering and Applied Sciences at Harvard University. His research interests include fundamental studies of micro/nanoscale heat and mass transport, fluid-structure interactions for phase change heat transfer and bubble/droplet/particle-surface interactions.
