Thermal-Fluid Science

Our thermal-fluid science faculty seek to understand and engineer the transport of matter and energy from the molecular to megawatt scale. Our work drives the creation of technologies that impact nearly every facet of modern life including providing clean electricity and water, enabling sustainable transportation, and improving the safety and efficiency of advanced electronics, energy storage, and manufacturing systems.

Transport Phenomena

We use a combination of experimental and simulation tools to understand the physics that govern the transport of mass, momentum and energy in different mediums and at multiple scales. Examples include understanding the flow through porous media, transport of particulates, boiling, condensation and supercritical heat transfer, reacting flows, and many more. These insights help improve applications ranging from computer chip cooling to the more efficient generation and storage of electricity from wind, water, solar, nuclear and conventional sources.

Advanced Computational Methods

Our faculty both develop and use new computational methods to study flows with complex phenomena such as chemical reactions, particle transport, and detonations. Research projects include developing numerical methods for large eddy simulation and direct numerical simulation of turbulent flows, and designing strategies for performing parallel simulations of combustion and reacting flows on high-performance computing clusters.

Combustion and Fire

Members of the TFS faculty use experiments and computational simulations to study combustion and fire phenomena relevant to applications in energy, transportation, aerospace, and the environment. Examples of research projects include understanding the combustion behavior of alternate fuels, studying what controls ignition and smoldering in wildfires, and improving models for fuel chemistry and combustion.

Applied Energy Systems

Our TFS faculty work on translating the fundamental insights and computational methods discussed above into components and systems that can be deployed into the market. This work is inherently interdisciplinary, and requires collaboration with experts in manufacturing, materials, economics, policy, and many others. Examples of our impact include the deployment of more efficient cook stoves in developing regions, development of new heat and mass exchanger technology that improves how buildings are cooled, chemical products are made and water is purified, and investigations on thermal and chemical grid-level energy storage critical for increasing the adoption of renewable energy sources.
