 August 4, 2008, 11:13 Re: stationary discontinuity #2 ag Guest   Posts: n/a A stationary shock is one example of a stationary discontinuity. Since shocks and contact surfaces can be moving through a fluid, the 'stationary' descriptor is prepended to denote the type of discontinuity being referenced. This also applies to other types of discontinuities.

 August 4, 2008, 12:33 Re: stationary discontinuity #4 mu Guest   Posts: n/a Stationary is a name then. What about if this discontinuity is a contact wave i.e. one eigenvalue for a system of conservation laws is it still a stationary discontinuity then?

 August 4, 2008, 14:42 Re: stationary discontinuity #5 ag Guest   Posts: n/a Generally no. The eigenvalue typically corresponds to the speed of the discontinuity.
