| Research Abstract |
A turbulence modeling for three-dimensional incompressible turbulent flows has been developed from a viewpoint of wavelet. Specifically,(A) comparison between wavelet nonlinear filtering and Fourier linear filtering for isotropic turbulence,(B) quantification of intermittency of anisotropic turbulence by the use of wavelet analysis, and(C) development of an adaptive wavelet method to simulate incompressible turbulence and its assessment for incompressible turbulent mixing layers in terms of savings of memory and CPU time, have been conducted.
