The lab studies instability, coherent structures and their role in turbulent flows and aeroacoustic sound generation. A central aim is to connect measurable flow patterns to the physical processes that sustain them, and to build models that are compact enough to interpret.<\/p>\n\n\n\n
Identifying the flow structures and instability mechanisms associated with noise generation, including the small, acoustically efficient part of turbulent jet fluctuations.<\/p>\n\n\n\n
Using mean-flow-based linear operators to model coherent structures in turbulent jets and wall-bounded flows, and examining the assumptions on which such models rest.<\/p>\n\n\n\n
Developing and applying modal methods that extract interpretable dynamics from experimental and numerical data, including data that are not time-resolved.<\/p>\n\n\n\n
Identifying reduced dynamical models from observations using delay coordinates, and learning corrections that make inexpensive simulations more useful.<\/p>\n\n\n\n
Our work brings together particle image and particle tracking velocimetry, direct and large-eddy numerical simulation, and reduced-order analysis. Methods include proper orthogonal decomposition (POD), dynamic mode decomposition (DMD), spectral POD (SPOD), resolvent analysis, Wiener\u2013Hopf techniques and delay-coordinate embedding.<\/p>\n\n\n\n
