In the two-dimensional case the Euler equations have global existence and uniqueness for initial data! 0 2L1. This result is due toYudovich (). For initial data in the space C1; the Euler equations are well-posed for short time in C1;. Moreover, the solution conserves energy. This result was originally proved byLichtenstein ().File Size: KB.

Also, complex problems with shocks and steep compression and expansion gradients may defy solution altogether. Upwind schemes are in general more robust but are also more involved in their derivation and application. Some upwind schemes that have been applied to the Euler equations are: [4], [5][3], [6]. @article{osti_, title = {PROTEUS two-dimensional Navier-Stokes computer code, version 1. 0.
