Abstract
Wavelet-based adaptive large-eddy simulation uses wavelet filtering to separate resolved from residual (more from less energetic) turbulent eddies, overcoming limitations of traditional lowpass filter-based methods that are not able to investigate the multi-resolution features and intermittency of turbulence. This is further developed by introducing a novel localized dynamic kinetic-energy-based model for wall-bounded turbulent compressible flows. Application to supersonic channel flow demonstrates the efficiency and accuracy of the method that is characterized by a high dynamic spatial-temporal adaptation, paving the way for modeling and simulation of complex engineering turbulent flows.
