Identifying regions of importance in wall-bounded turbulence through explainable deep learning
Andres Cremades, Sergio Hoyas, Rahul Deshpande +8
Despite its great scientific and technological importance, wall-bounded turbulence is an unresolved problem in classical physics that requires new perspectives to be tackled. One o…
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…
Active and inactive components of the streamwise velocity in wall-bounded turbulence
Rahul Deshpande, Jason P. Monty, Ivan Marusic
Townsend (1961) introduced the concept of active and inactive motions for wall-bounded turbulent flows, where the active motions are solely responsible for producing the Reynolds s…
A spectral-scaling based extension to the attached eddy model of wall-turbulence
D. Chandran, J. P. Monty, I. Marusic
Two-dimensional (2-D) spectra of the streamwise velocity component, measured at friction Reynolds numbers ranging from 2400 to 26000, are used to refine a model for the logarithmic…
Model-Based Estimation of Vortex Shedding in Unsteady Cylinder Wakes
Jiwen Gong, Jason P. Monty, Simon J. Illingworth
This paper considers single-sensor estimation of vortex shedding in cylinder wakes at in simulations and at in experiments. A model based on harmonic decompositi…
Two-dimensional energy spectra in high Reynolds number turbulent boundary layers
Dileep Chandran, Rio Baidya, Jason P. Monty +1
Here we report the measurements of two-dimensional (2-D) spectra of the streamwise velocity () in a high Reynolds number turbulent boundary layer. A novel experiment employing m…
Sea ice floes dissipate the energy of steep ocean waves
Alessandro Toffoli, Luke G. Bennetts, Michael H. Meylan +4
Wave attenuation by ice floes is an important parameter for modelling the Arctic Oceans. At present, attenuation coefficients are extracted from linear models as a function of the…
Spatially developing turbulent boundary layer on a flat plate
J. H. Lee, Y. S. Kwon, N. Hutchins +1
This fluid dynamics video submitted to the Gallery of Fluid motion shows a turbulent boundary layer developing under a 5 metre-long flat plate towed through water. A stationary ima…
