Abstract
For computational aeroacoustics (CAA), schemes with low dissipation and dispersion errors are a necessity. This is because of the small amplitude of the acoustic waves and because of the large distances over which they have to travel. Also, non-reflecting boundary conditions play a very important role, since spurious reflections could significantly reduce the quality of the solution. To damp out small spurious waves that might occur, Artificial Selective Damping (ASD) can be used. In this paper, the performance for CAA of a fourth order central compact finite volume scheme, in combination with ASD and two different sets of boundary conditions, is investigated.
