摘要：

We use the Legendre spectral viscosity method to solve nonlinear conservation laws. This method essentially consists in adding a spectral viscosity to the equations for the high wavenumbers of the numerical solution. This viscosity is sufficient to stabilize the numerical scheme while small enough to retain spectral accuracy. Several tests are considered including the 1D and 2D Euler equations Of gas dynamics.
