Abstract
Two artificial dissipation models, the original model of Jameson, Schmidt and Turkel. and its modification by Martinelli. are applied to compute vortex breakdown on a delta wing. The original model can add too much of13; artificial dissipation along grid directions having smaller spectral radii. The non-isotropic form of the latter model provides a better control over the artificial dissipation that is added along each grid direction. The computations presented in the paper show that the latter model gives a more accurate prediction of the flow on a given grid.
