Speaker: Kyungwoo Song, Kyung Hee University
Abstract: We introduce a pressure-gradient system derived from the two-dimensional compressible Euler system and we construct patches of solutions of the 2-D Riemann problems for the pressure-gradient system. In the self-similar plane, we verify that there are elliptic regions, hyperbolic regions, and sonic boundary parts. In addition, it is also verified that there is a zone called semi-hyperbolic or partially hyperbolic in which one family out of two nonlinear families of characteristics starts on sonic curves and ends on transonic shock waves.
