摘要：
The wavelet-based multi-resolution analysis technique is used to develop it novel approach to the modelling of the sub-grid terms in large-eddy simulation equations. This new approach is called WaveLES. A numerical framework for the solution of the projected equations is developed for one and three-dimensional problems. The WaveLES method is assessed in a priori tests on art atmospheric turbulent time series, and a. direct numerical simulation. 4 posteriori tests are carried out for the Burgers equation.
