A Hydrodynamic Model of a Magnetized Jet Flow in the Magnetosphere

A new hydrodynamic model of a quasi-stationary jet is presented. Approximation of the ideal hydrodynamics of an incompressible fluid is found using an analytical solution, corresponding to a jet limited in space, under conditions of compensation for the nonlinear effects of velocity and magnetic field in the equation of motion. An axially symmetric low-parameter model of a stationary jet was created for the boundary conditions typical for jets in astrophysics and in laboratory modeling experiments, which makes it possible to describe the structure of the velocity field and magnetic field.
