Combustion instability
Thermoacoustic transitions, flame dynamics, synchronization, and instability mechanisms in reacting flows.
Reacting flow, instability, and nonlinear dynamics
Yue Weng
I am an Assistant Professor in the Department of Aerospace Engineering at Mississippi State University. I study how flames, flows, and complex dynamical systems organize, transition, and become unstable.
Research Interests
How coherent behavior emerges in fluid and flame systems
Complex systems
Nonlinear dynamics, bifurcations, coherent structures, and reduced descriptions of high-dimensional flows.
Flow imaging
Advanced diagnostics including digital holography, 3D particle tracking velocimetry, and data-rich experiments.
