Research Area: Fluid Dynamics

In the Thermofluids Group, we create models of fluid flow to help produce cleaner power, conserve energy, and understand structural instability. We also make measurements using advanced optics to interrogate complex fluids and nano-particle suspensions. Our research employs some of the world's largest computers in order to simulate the complex flows occurring in nature and engineered systems. We combine these simulations with laser-based experimental diagnostics from our experimental laboratories to reveal comprehensive images of velocity, pressure, and temperature.

Research Laboratories

Fluid Structure Interactions Laboratory

We work on various aspects of Fluid-Structure Interactions, Nonlinear Dynamics, and Biomimetics. View current research projects here.

Multiphase Flow Simulation Lab

Power is fundamental to the existence of modern society. Without power, you couldn't be reading this web page, for example. However, the environmental consequences of our current methods of power generation are unsustainable. Our lab seeks to improve the performance and reduce the emissions of modern power systems by better understanding of the fuel/air mixing.

The research of the Multiphase Flow Simulation Lab include sprays, cavitation, and other multiphase flows. These studies combine the intellectual challenge of multiple phenomena interacting at multiple scales, and provide the long-term benefits to society of cleaner and more efficient power. For diesel and jet engines, the spray quality has a tremendous impact on the emissions. We also simulate sprays in rockets, where we have great difficulty predicting and controlling the combustion process.

Non-Newtownian Fluid Dynamics Lab

The Non-Newtownian Fluid Dynamics Lab is actively involved in research in a number of different areas including: the dynamics of complex fluids; laminar and turbulent drag redution; the development and utilization of superhydrophobic surfaces; shear and extensional rheology of a number of different complex fluids; non-Newtonian fluid dynamics; microfluidics; nanotechnology; non-isothermal flows; hydrodynamic stability; and polymer processing. On our lab website, you will find a number of short examples of active research along with links to the corresponding publications and graduate students responsible for the work.

Theoretical and Computational Fluid Dynamics Lab

The Theoretical and Computational Fluid Dynamics Laboratory is dedicated to the development of practical and generally applicable tools for the prediction of complex and often chaotic fluid flows.

Research at the Lab is focused on the entire CFD food chain from hardware and software to algorithms and turbulence models.  Understanding in detail how the computational, mathematical, and physical problems of CFD interact is the key to designing lasting CFD solutions.

Turbulence Simulation Laboratory

To study the details of a turbulent flow, it is sometimes more informative to accurately simulate the flow with a computer than to try to observe it in the laboratory. Direct numerical simulation involves the numerical solution of the equations that govern fluid flows.  It is a research tool that provides us with an extremely detailed description of the flow field.  Our lab uses these techniques to study various flows...Read More
