  In this paper, we establish the existence of three-dimensional axisymmetric
compressible jet flows for steady Euler system with large vorticity by using
the variational method. More precisely, for given axial velocity of the flow at
the upstream, if the mass flux is sufficiently large, we can find a unique
outer pressure such that a smooth subsonic three-dimensional axisymmetric jet
flow with large vorticity exists and has certain far fields behavior.
