Prediction of equivalent sand-grain size and identification of drag-relevant scales of roughness -- a data driven approach
Jiasheng Yang, Alexander Stroh, Sangseung Lee +3
The purpose of the present work is to examine two possibilities; firstly, predicting equivalent sand-grain roughness size based on the roughness height probability density fu…
DNS-based characterization of pseudo-random roughness in minimal channels
Jiasheng Yang, Alexander Stroh, Daniel Chung +1
Direct numerical simulation is used to study turbulent flow over irregular rough surfaces in the periodic minimal channel configuration. The generation of irregular rough surface i…
Predicting drag on rough surfaces by transfer learning of empirical correlations
Sangseung Lee, Jiasheng Yang, Pourya Forooghi +2
Recent developments in neural networks have shown the potential of estimating drag on irregular rough surfaces. Nevertheless, the difficulty of obtaining a large high-fidelity data…
