The UNBF Physics Department Seminar will be held on Thursday, Sept. 20, from 1:15 - 2:15 p.m., in the Physics Admin Room, 204.

Amy-Rae Gauthier, UNBF Physics, will discuss "Developing a Diffusion Tensor Imaging Technique for Turbulent Flow."

Details: “We are like dwarfs on the shoulders of giants, so that we can see more than they…” – Bernard de Chartres.  

This seminar will cover the continuation of our work developing the Diffusion Tensor Imaging technique for application to turbulent flow systems. Turbulence is found in many physical situations including weather phenomena, factory pipelines, blood vessels, wind turbines, airplanes, etc. The goal of this research is to develop a measurement technique that can characterize turbulence in a quantitative and useful way to better understand this ubiquitous phenomenon. We will start by building the model which allows us to characterize turbulence as an “eddy self diffusivity tensor.” We will then consider how we can measure this eddy self diffusivity tensor using magnetic resonance imaging (MRI). Next, we will delve into the experimental side of things to see how such measurements are done in the lab. Lastly, we will look at the results of such a measurement and draw a conclusion or two regarding the nature of turbulent flow in the system studied.

Please join us for Colloquium tea in P203 beforehand.
