| Abstract: | This paper studies the Riemann problem for two-dimensional steady zero-pressure isentropic flow with three constant states as initial data. With the help of characteristic analysis, under suitable generalized Rankine-Hugoniot relation and entropy condition, four different structures of Riemann solutions are established uniquely, in which the interactions among delta shock wave, vacuum and contact discontinuity are clarified. |
