| Spanish abstract | En este articulo se resume la fisica conocida sobre los chorros turbulentos observados en experimentos de laboratorio. La formula para la potencia liberada como turbulencia describe la concentraci on turbulencia/part culas relativistas en cada punto del chorro astrof sico. Se usa la misma expresi on para analizar la po- tencia liberada como turbulencia para u dos de tubo y no-newtonianos. Mediante una operaci on integral es posible deducir la intensidad de la radiaci on sincrotr onica para un per l perpendicular (o no) a un chorro recto, obtener un mapa 2D para un chorro perpendicular de orientaci on arbitraria, as como mapas 2D para trayecto- rias complejas como es el caso de NGC 4061 y 3C31. Se presenta una simulaci on del ndice espectral del brillo para 3C273, as como un mapa 2D del grado de po-larizacion lineal. Se aplica el operador Sobel a los mapas 2D te oricos para chorros rectos perpendiculares |
| English abstract | This paper summarizes the known physics of turbulent jets observed in lab- oratory experiments. The formula, which gives the power released in turbulence describes the concentration of turbulence/relativistic particles in each point of the astrophysical jets. The same expression is also used to analyze the power released in turbulence in the case of pipe and non-Newtonian uids. Through an integral operation it is possible to deduce the intensity of synchrotron radiation for a pro le perpendicular (or not) to a straight jet, a 2D map for a perpendicular, randomly oriented straight jet, as well as a 2D map of complex trajectories such as NCC 4061 and 3C31. Presented here is a simulation of the spectral index in brightness of 3C273 as well as a 2D map of the degree of linear polarization. The Sobel operator is applied to the theoretical 2D maps of straight perpendicular jets |
