Abstract

The stochastic coherent adaptive large eddy simulation (SCALES) method [3] exploits a wavelet thresholding filter- ased dynamic grid adaptation strategy to solve for the energetic “coherent” eddies in a turbulent flow field. The effect of the residual less energetic flow structures is modeled by supplying the simulation with a suitable subgrid-scale (SGS) model. The SCALES approach was successfully applied to the simulation of decaying homogeneous turbulence (e.g., see [2, 10]). Here, the wavelet-based approach is applied to statistically steady turbulence by considering linearly forced homogeneous turbulence at moderate Reynolds-number.
