Predicting the near-wall region of turbulence through convolutional neural networks

no code implementations15 Jul 2021 A. G. Balasubramanian, L. Guastoni, A. Güemes, A. Ianiro, S. Discetti, P. Schlatter, H. Azizpour, R. Vinuesa

At $Re_{\tau}=550$, the FCN can take advantage of the self-similarity in the logarithmic region of the flow and predict the velocity-fluctuation fields at $y^{+} = 50$ using the velocity-fluctuation fields at $y^{+} = 100$ as input with less than 20% error in prediction of streamwise-fluctuations intensity.

Convolutional-network models to predict wall-bounded turbulence from wall quantities

no code implementations22 Jun 2020 L. Guastoni, A. Güemes, A. Ianiro, S. Discetti, P. Schlatter, H. Azizpour, R. Vinuesa

Two models based on convolutional neural networks are trained to predict the two-dimensional velocity-fluctuation fields at different wall-normal locations in a turbulent open channel flow, using the wall-shear-stress components and the wall pressure as inputs.

Prediction of wall-bounded turbulence from wall quantities using convolutional neural networks

no code implementations30 Dec 2019 L. Guastoni, M. P. Encinar, P. Schlatter, H. Azizpour, R. Vinuesa

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-shear-stress planes in a turbulent open channel flow.
