Data-driven enhancement of coherent structure-based models for predicting instantaneous wall turbulence
Rahul Deshpande, Charitha M. de Silva, Myoungkyu Lee +2
Predictions of the spatial representation of instantaneous wall-bounded flows, via coherent structure-based models, are highly sensitive to the geometry of the representative struc…
Reynolds stress scaling in the near-wall region of wall-bounded flows
Alexander J. Smits, Marcus Hultmark, Myoungkyu Lee +2
A new scaling is derived that yields a Reynolds number independent profile for all components of the Reynolds stress in the near-wall region of wall bounded flows, including channe…
Reynolds stress scaling in the near-wall region
Alexander J. Smits, Marcus Hultmark
A new scaling is derived that yields a Reynolds number independent profile for all components of the Reynolds stress in the near-wall region of wall bounded flows. The scaling demo…
Scaling turbulence in the near-wall region
Marcus Hultmark, Alexander J. Smits
A new velocity scale is derived that yields a Reynolds number independent profile for the streamwise turbulent fluctuations in the near-wall region of wall bounded flows for $y^+<2…
Life-cycle of streaks in the buffer layer of wall-bounded turbulence
H. Jane Bae, Myoungkyu Lee
Streaks in the buffer layer of wall-bounded turbulence are tracked in time to study their life-cycle. Spatially and temporally resolved direct numerical simulation data is used to…
