摘 要: | Two-Dimensional Regular Shock Reflection for the Pressure Gradient System of Conservation Laws - Yuxi Zheng We establish the existence of a global solution to a regular reflection of a shock hitting a ramp for the pressure gradient system of equations. The set-up of the reflection is the same as that of Mach's experiment for the compressible Euler system, i.e., a straight shock hitting a ramp. We assume that the angle of the ramp is close to 90 degrees. The solution has a
