چکیده انگلیسی
In this report we consider the problem of the existence of global attractors of the weak solution of the approximate deconvolution models of turbulence. The L2-global attractors are known to exist for large eddy simulation models such as Leray-alpha, Leray-deconvolution or NS-omega models. In the case of the approximate deconvolution model, as the L2 norm of the weak solution of the ADM is not controlled by the L2-norm of the initial data and the approximate deconvolution model is an approximation of the filtered NSE, we are led to the question of existence of H1-global attractors. We also prove better regularity of the weak solution of ADM.
