Based on the viscous MHD model [Shatashvili & Yoshida 2011] we have studied the astrophysical disk-jet structure formationproblem in two-fluid approximation. We constructed the analytical self-similar solutions for both the non-relativistic and the relativistic electron-fluid cases, in the latter case pressure is modified by the relativistic effects. We have analyzed the distributions of main physical quantities, results of which clearly show the well-collimated disk-jet structure. We have studied in detail the roles of two-fluid and relativistic effects in the jet collimation – both effects contribute significantly in the Jet material accumulation as well as in the collimation. Results of given thesis are in good agreement with observational data.
