Abstract: (arXiv)
We present a ballistic description of the formation and propagation of the working surface of a relativistic jet. Using simple laws of conservation of mass and linear momentum at the working surface, we obtain a full description of the working surface flow parametrised by the initial velocity and mass injection. This allows us to compute analytically the energy release at any time in the working surface. We compare this model with a new numerical code used for the propagation of a relativistic fluid in one dimension. We finally use this code to test the limits of our study.
