Simple Waves and a Characteristic Decomposition of the Two Dimensional Compressible Euler Equations

Jiequan Li, Tong Zhang, and Yuxi Zheng

Abstract: We present a characteristic decomposition of the potential flow equation in the self-similar plane. The decomposition allows for a proof that any wave adjacent to a constant state is a simple wave for the adiabatic Euler system. This result is a generalization of the well-known result on 2-d steady potential flow and a recent similar result on the pressure gradient system.
