Data-driven approach for modeling Reynolds stress tensor with invariance preservation
Xuepeng Fu, Shixiao Fu, Chang Liu +2
The present study represents a data-driven turbulent model with Galilean invariance preservation based on machine learning algorithm. The fully connected neural network (FCNN) and…
Spatial input-output analysis of large-scale structures in actuated turbulent boundary layers
Chang Liu, Igal Gluzman, Mitchell Lozier +4
This paper develops a spatial input-output approach to investigate the dynamics of a turbulent boundary layer subject to a localized single frequency excitation. This method uses o…
Structured input-output analysis of transitional wall-bounded flows
Chang Liu, Dennice F. Gayme
Input-output analysis of transitional channel flows has proven to be a valuable analytical tool for identifying important flow structures and energetic motions. The traditional app…
An input-output based analysis of convective velocity in turbulent channels
Chang Liu, Dennice F. Gayme
This paper employs an input-output based approach to analyze convective velocities and the transport of fluctuations in turbulent channel flows. The convective velocity for a fluct…
