Magnetohydrodynamic Modeling of Relativistic Outflows


Vlahakis N. Magnetohydrodynamic Modeling of Relativistic Outflows. [Internet]. 2008;17:1661 - 1668.


The main characteristics of relativistic, steady, ideal magnetohydrodynamic (MHD) outflows are discussed, focusing on their bulk acceleration and collimation. It is shown that the Bernoulli equation relates the bulk Lorentz factor with the shape of the flow, permitting an analytic estimation of the acceleration efficiency, while the transfield force-balance equation gives a simple relation of the bulk Lorentz factor to the distance.
