Abstract
The Blandford and Rees (BR) beam model for extra-galactic radio sources is critically examined within the context of axisymmetric, non-relativistic ideal gas dynamics. Thus we assume that radio jets contain thermal matter that governs the structure and dynamics of the jet. We conduct numerical experiments that study the structure and stability of the 3 basic jet components conceived by BR-beam, working surface and cocoon – for various beam Mach numbers and temperature ratios with respect to a constant ambient medium (the intergalactic medium). Jets are established by continuously injecting a collimated supersonic beam of gas into, and in pressure equilibrium with, the ambient medium.
