Towards Wavelet-Based Intelligent Simulation of Wall-Bounded Turbulent Compressible Flows

Abstract

The progress in the development of a wavelet-based intelligent modelling and simulation framework, capable of performing adaptive simulations of wall-bounded turbulent compressible flows, is discussed. A novel split mesh adaptation strategy based on mean and fluctuating components is introduced and tested. The preliminary results that are achieved for the transitional supersonic channel with isothermal walls are very promising. It is demonstrated that the new strategy is very efficient when dealing with inhomogeneous wall-bounded flows, in terms of resolving coherent flow structures, while substantially reducing the number of degrees of freedom, without loss of the solution fidelity.
