Thermal/Fluid Sciences

We are developing ways to extract energy from fluid flows and heat exchange.

Faculty and students working in the thermal/fluid sciences advance the understanding of systems that involve thermodynamic conversions of energy, the conversion of the flow of liquids and gases into force and power, and heat exchange. Our research focuses on the conversion of energy from fuel and from the flow of wind and water for use in industry, transportation, buildings, and homes. Our fundamental studies in thermodynamics, heat transfer, fluid dynamics, turbomachinery, energy storage, and combustion are applied to improve engines, gas turbines, wind turbines and wind farms, hydro turbines, power plants, and energy storage devices. We conduct large-scale experiments and apply high performance computing methods to advance scientific understanding, mathematical modeling, and design tools.
