Resonance phenomenon for the Galerkin-truncated Burgers and Euler equations.
It is shown that the solutions of inviscid hydrodynamical equations with suppression of all spatial Fourier modes having wave numbers in excess of a threshold K(G) exhibit unexpected features. The study is carried out for both the one-dimensional Burgers equation and the two-dimensional incompressible Euler equation. For large K(G) and smooth initial conditions, the first symptom of truncation,...
متن کاملWavelet Galerkin Methods for Aerosol Dynamic Equations in Atmospheric Environment
Aerosol modelling is very important to study and simulate the behavior of aerosol dynamics in atmospheric environment. In this paper, we consider the general nonlinear aerosol dynamic equations which describe the evolution of the aerosol distribution. Continuous time and discrete time wavelet Galerkin methods are proposed for solving this problem. By using the Schauder’s fixed point theorem and...
متن کاملWavelet Galerkin methods for second-kind integral equations
We use vector-valued multiwavelets on compact sets to develop a Galerkin method for systems of integral equations of the second kind. We propose a compression strategy for the coeflieient matrix of the linear system obtained from this method and show that the compressed scheme preserves almost optimal convergence rate of the original scheme and yields a sparse matrix with a bounded condition nu...
متن کاملGalerkin Based Wavelet Methods for Solutions of Differential Equations
Solutions of numerical differential equations based on orthogonal functions is a quite classical (old) method. Also wavelets being orthogonal functions have been applied to such problems. In recent years there has been increasing attempt to find solutions of differential equations using wavelet techniques. In this chapter, we elaborate various waveletGalerkin methods such as Amaratunga et al. m...
متن کاملWavelet Regularization of a Fourier-galerkin Method for Solving the 2d Incompressible Euler Equations
We employ a Fourier-Galerkin method to solve the 2D incompressible Euler equations, and study several ways to regularize the solution by wavelet filtering at each timestep. Real-valued orthogonal wavelets and complex-valued wavelets are considered, combined with either linear or nonlinear filtering. The results are compared with those obtained via classical viscous and hyperviscous regularizati...
