Self-sustaining Food/Energy/Water system for saline coastal regions Lei Zuo Professor, John R. Jones III Faculty Fellow Research Focus: Ocean wave energy harvest- ing (EH); EH vehicle shock absorbers; Thermoelectric energy genera- tors for vehicle applications; EH from rail- way vibrations In this US-China collaborative project, five researchers in multidisciplinary areas from Virginia Tech, Wuhan University of Technology in China, and Nanjing Agricul- tural University in China will team up to create a self-sustainable FEW System in saline coastal regions. This system will be realized through the integration of three areas of innovation: 1) Wave energy-based seawater desalination systems, 2) sustain- able reclamation of saline-sodic-alkaline soils, and 3) a nexus of ocean energy, freshwater, and coastal agriculture. Specific research tasks include: 1) Modeling and design of a novel ocean wave surge energy converter and an ocean wave energy powered desalination system; (2) Modeling of coastal salt-soil-water balance dynamics and optimizing soil reclamation manage- ment and agriculture irrigation specific to coastal regions; and (3) Development of a supply-de- mand model for the FEW System to estimate the optimal operation conditions for each system, followed by conducting field tests and verification. If successful, the proposed research will convert traditional coastal agriculture from a freshwater- and energy-consuming practice into a self-sustainable, environmentally friendly practice that balances ecosystems. Non-invasive Thermal Interrogation Thomas Diller Professor Non-Invasive Thermal Interrogation (NITI) is a form of non-destructive testing that uses simultaneous combinations of surface heat flux and surface temperature signals. When these measurements are combined with signal processing algorithms, such as parameter estimation routines or other techniques, they can be used to non-invasively determine the internal temperature and properties of different objects and systems. Consequently, NITI has many practical applications in the biomedical, industrial, and wearable arenas. Research Focus: Development and use of new instrumentation for measuring heat transfer. Applications include high- temperature unsteady flows, such as found in gas turbine engines, re- entry vehicles, and combus- tion environ- ments Revised and Corrected, Nov. 2019 21
