Prediction of wall-bounded turbulence from wall quantities using convolutional neural networks
L. Guastoni, M. P. Encinar, P. Schlatter +2
A fully-convolutional neural-network model is used to predict the streamwise velocity fields at several wall-normal locations by taking as input the streamwise and spanwise wall-sh…
Edge tracking in spatially developing boundary layer flows
Miguel Beneitez, Yohann Duguet, Philipp Schlatter +1
Recent progress in understanding subcritical transition to turbulence is based on the concept of the edge, the manifold separating the basins of attraction of the laminar and the t…
Coherent structures and secondary flow in turbulent square duct
Marco Atzori, Ricardo Vinuesa, Adrián Lozano-Durán +1
The aim of the present work is to investigate the role of coherent structures in the generation of the secondary flow in a turbulent square duct. The coherent structures are define…
Predictions of turbulent shear flows using deep neural networks
P. A. Srinivasan, L. Guastoni, H. Azizpour +2
In the present work we assess the capabilities of neural networks to predict temporally evolving turbulent flows. In particular, we use the nine-equation shear flow model by Moehli…
Unsteady aerodynamic effects in small-amplitude pitch oscillations of an airfoil
Prabal S. Negi, Ricardo Vinuesa, Ardeshir Hanifi +2
High-fidelity wall-resolved large-eddy simulations (LES) are utilized to investigate the flow-physics of small-amplitude pitch oscillations of an airfoil at Re = 100,000. The inves…
Turbulent boundary layers around wing sections up to Rec = 1,000,000
R. Vinuesa, P. S. Negi, M. Atzori +3
Reynolds-number effects in the adverse-pressure-gradient (APG) turbulent boundary layer (TBL) developing on the suction side of a NACA4412 wing section are assessed in the present…
