一个关于超音速钝体的问题
In supersonic blunt body problem, the sudden change in nature of the Euler equations across the sonic line cause the flow region seperating into subsonic and supersonic region, which have totally different mathematical behavior of elliptic and hyperbolic equations.
To tackle this problem, Moretti and Abbett in 1966 use time as an additional indepent variable, the governing Euler equations become hyperbolic with respect to time, thus allowing a straightforward marching solution in time.
My question is:
How can we make sure that the proper steady flow results appearing in the limit of large times?
