What we do
At the Turbulence Simulation and Modeling (TSM) Lab at Michigan State University, we understand the fundamentals of turbulence through large-scale, high-fidelity simulations and develop next-gen physics- or data-based predictive methods. Applications are in engineering and environmental problems that prove challenging for traditional predictive approaches.
Specifically, we are interested in complex, realistic wall-bounded turbulent flows, such as those with pressure gradients, unsteadiness, surface roughness, rotation, compressibility, multiple phases, etc. One can find such flows in turbomachinery, vehicles, animal locomotions, rivers, the atmosphere, just to name a few.

About Prof. Yuan
Dr. Yuan is an Associate Professor in Department of Mechanical Engineering at Michigan State University. She obtained both MS and PhD degrees (2015) in from Queen's University, Canada. She developed large-scale, high-fidelity numerical simulation methods of wall-bounded turbulent flows with complex boundary geometry. Her research goal is to push the boundaries of physical understandings of complex, realistic turbulence, and to develop physic-based and empirical closures for a wide range of applications. Topics include non-equilibrium turbulence, wall roughness, wall permeability, turbulence-induced noise, and fluid-structure interaction. Applications cover engineering, environmental and bio-locomotive topics. Her research group is funded by ONR, NSF and the industry. She serves on proposal review panels and as reviewers for numerous journals. She is also actively involved in outreach program such as the High School Engineering Institute.
