We face the numerical solution of Navier-Stokes equations for compressible viscous flows in a two-dimensional domain. Equations are advanced in time by two different semi-implicit methods, each of them yielding at each step a transport equation for the flow density, and a scalar advection-diffusion equation for each velocity component. These equations are approximated by multidomain spectral collocation methods. Numerical results for two test cases are presented.

Abstract
We face the numerical solution of Navier-Stokes equations for compressible viscous flows in a two-dimensional domain. Equations are advanced in time by two different semi-implicit methods, each of them yielding at each step a transport equation for the flow density, and a scalar advection-diffusion equation for each velocity component. These equations are approximated by multidomain spectral collocation methods. Numerical results for two test cases are presented.File in questo prodotto:
