Enhanced Forced Convection Heat Transfer using Flow-Driven, Aeroelastically Vibrating Reeds
Thermal management has become a major limiting challenge for current and future high-performance electronic systems, such as high-speed microprocessors, power converters, micro- and millimeter-wave power electronics, optoelectronics, etc. In this project, we develop detailed fully coupled Flow-Structure-Thermal (CFST) solver in order to investigate the implementation, design, and optimization of aeroelastically-driven self-oscillating reeds (SORs) for improving the heat transfer characteristics within high-aspect-ratio channels of air-side heat exchangers.

Harvesting Energy from Flow-Induced Flutter
Recent years have seen a tremendous increase in the use of small-scale sensors and sensor networks for a wide variety of applications ranging from measurement/monitoring of environmental conditions to in-situ tracking of wild animals. Most of these devices require small amounts of power, but the key in the effective functioning of these devices is the ability to provide power over time-spans extending over many months and even years. In this project, we use a multidisciplinary approach that combines computational modeling, advanced manufacturing and experimental testing to answer key questions regarding the performance and optimization of the piezoelectric Energy Harvesting systems for these applications.
