A Physics-Informed Vector Quantized Autoencoder for Data Compression of Turbulent Flow

1 code implementation10 Jan 2022 Mohammadreza Momenifar, Enmao Diao, Vahid Tarokh, Andrew D. Bragg

In this study, we apply a physics-informed Deep Learning technique based on vector quantization to generate a discrete, low-dimensional representation of data from simulations of three-dimensional turbulent flows.

When is settling important for particle concentrations in wall-bounded turbulent flows?

no code implementations12 Jan 2021 Andrew D. Bragg, David H. Richter, Guiquan Wang

While it may be thought that settling can be ignored when the settling parameter $Sv\equiv v_s/u_\tau$ is small ($v_s$ - Stokes settling velocity, $u_\tau$ - fluid friction velocity), we show that even in this regime the settling may make a leading order contribution to the concentration profiles.
