KSEF RDE: Multi-component nano-scale thermal anemometyr probe for turbulence measurement

Funds are requested to develop multi-component nano-scale thermal anemometry probes for conducting turbulence measurements at unprecedented spatial and temporal resolution. These probe will be manufactured using a series of semiconductor manufacturing steps to produce two or more free-standing 2micron x 60micron x 800nm platinum nanowires suspended between aerodynamically shaped support structures. By arranging multiple nanowires in select arrangements on a single probe body it will be possible to create probe configurations capable of simultaneous measurements of multiple velocity components and temperature with high temporal and spatial resolution. The probes manufactured as part of this research will then be used to conduct detailed investigations of the structure and organization of a high Reynolds number turbulent wall-bounded flow. Information advancing our understanding and prediction ability for such flows offers societal improvements in many ways, such as reduced fuel consumption for air and water vehicles, reduced manufacturing costs through more efficient pipe flow, improved energy recovery in wind turbines and heat exchangers and improved modeling of weather and climate patterns.
