Transonic shocks for 3-D axisymmetric compressible inviscid flows in cylinders

Hyangdong Park, Hyeongyu Ryu

We establish the existence of an axisymmetric weak solution to the steady Euler system with a transonic shock, nonzero vorticity, and nonzero swirl in a three-dimensional cylinder.…

Contact discontinuities for 3-D axisymmetric inviscid compressible flows in infinitely long cylinders

Myoungjean Bae, Hyangdong Park

We prove the existence of a subsonic axisymmetric weak solution $(u, ρ, p)$ with $u = u_{x} e_{x} + u_{r} e_{r} + u_{θ} e_{θ}$ to steady Euler system in a three-dimensional…
