Space-time Description of Supersonic Jets with Thermal Non-uniformity
… boundary condition to produce changes in the turbulence development and decrease the acoustic efficiency of coherent structures. The research presented here focuses on a novel jet noise reduction technique involving a centered thermal non-uniformity that alters the base flow by introducing a …

Three-dimensional turbulence mechanisms in a supersonic separated/reattaching longitudinal cylinder wake
… work provides a detailed characterization of the turbulence structure in the near-wake of a blunt-based cylinder aligned at zero angle-of-attack in a Mach 2.49 freestream. Particular emphasis is placed in this work on the identification of turbulence mechanisms in the flow regions both upstream …

Description of Coherent Structures in the Atmospheric Boundary Layer By Model Reduction of the Surface Pressure
<p>The flow of coherent turbulent structures into a wind turbine is associated with vibrational blade excitation. Successful forecasting of such turbulent events for control system input would increase the lifetime of turbine components. The coherence of these features suggests description by model …
