Geometric Structures of Pseudo-Sonic Curves in Self-Similar Solutions of the Euler Equations for Potential Flow

Gui-Qiang G. Chen, Mikhail Feldman, Xin Gao +1

We are concerned with the geometric structures of pseudo-sonic curves in two-dimensional self-similar solutions for the Euler equations for potential flow, allowing for non-uniform…

Low Regularity of Self-Similar Solutions of Two-Dimensional Riemann problems with Shocks for the Isentropic Euler system

Gui-Qiang G. Chen, Mikhail Feldman, Wei Xiang

We are concerned with the low regularity of self-similar solutions of two-dimensional Riemann problems for the isentropic Euler system. We establish a general framework for the ana…

Steady supersonic combustion flows with a contact discontinuity in two-dimensional finitely long nozzles

Junlei Gao, Feimin Huang, Jie Kuang +2

In this paper, we are concerned with the two-dimensional steady supersonic combustion flows with a contact discontinuity moving through a nozzle of finite length. Mathematically, i…

Convergence Rate of the Hypersonic Similarity for Two-Dimensional Steady Potential Flows with Large Data

Gui-Qiang G. Chen, Jie Kuang, Wei Xiang +1

We establish the optimal convergence rate of the hypersonic similarity for two-dimensional steady potential flows with {\it large data} past over a straight wedge in the $BV\cap L^…
