A source-term interpretation of turbulent rough wall-pressure spectra
J. M. O. Massey, A. J. Smits, B. J. McKeon
Wall-pressure fluctuations beneath a turbulent boundary layer drive the flow-induced noise and structural loading of rough surfaces. On a smooth wall their variance grows with the…
An Inner-Scaled Linear Contribution to Wall-Pressure Variance at High Reynolds Number
J. M. O. Massey, S. J. Zimmerman, J. C. Klewicki +1
In canonical turbulent wall-bounded flows, the inner-scaled wall-pressure variance is empirically well described by a constant offset plus a slope logarithmic in the friction Reyno…
On the Poisson-Source Basis of Logarithmic Wall-Pressure-Variance Growth
Jonathan M. O. Massey, Joseph C. Klewicki, Beverley J. McKeon
In high-Reynolds-number wall-bounded flows, the inner-scaled wall-pressure variance \ra{is often represented as a} logarithmic increase with frictional Reynolds number. We consider…
Data-Augmented Resolvent Analysis of Wall-Bounded High-Pressure Transcritical Flow
M. Bernades, J. M. O. Massey, B. J. McKeon +1
High-pressure transcritical fluid flows are central to modern energy and propulsion systems. A key challenge arises in confined configurations, where optimizing performance require…
Two-component inner--outer scaling model for the wall-pressure spectrum at high Reynolds number
Jonathan M. O. Massey, Alexander J. Smits, Beverley J. McKeon
Wall-pressure fluctuations beneath turbulent boundary layers drive noise and structural fatigue through interactions between fluid and structural modes. Conventional predictive mod…
Resolvent analysis of a swimming foil
Jonathan M. O. Massey, Sean Symon, Bharathram Ganapathisubramani +1
This study employs resolvent analysis to explore the dynamics and coherent structures in the boundary layer of a foil that swims via a travelling wave undulation. A modified NACA f…
