  • Influence of internal energy on the stability of relativistic flows 
    Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Sol, Helene (2002-12-05)
    A set of simulations concerning the influence of internal energy on the stability of relativistic jets is presented. Results show that perturbations saturate when the amplitude of the velocity perturbation approaches the ...
  • Nonlinear stability of relativistic sheared planar jets 
    Perucho, Manuel; Marti, Jose-Maria; Hanasz, Michał (2005-10-14)
    The linear and non-linear stability of sheared, relativistic planar jets is studied by means of linear stability analysis and numerical hydrodynamical simulations. Our results extend the previous Kelvin-Hemlholtz stability ...
  • Resonant Kelvin-Helmholtz modes in sheared relativistic flows 
    Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Miralles, Juan-Antonio (2007-05-03)
    Qualitatively new aspects of the (linear and non-linear) stability of sheared relativistic (slab) jets are analyzed. The linear problem has been solved for a wide range of jet models well inside the ultrarelativistic domain ...
  • Stability of hydrodynamical relativistic planar jets. II. Long-term nonlinear evolution 
    Perucho, Manuel; Marti, Jose-Maria; Hanasz, Michał (2004-07-28)
    In this paper we continue our study of the Kelvin-Helmholtz (KH) instability in relativistic planar jets following the long-term evolution of the numerical simulations which were introduced in Paper I. The models have been ...
  • Stability of hydrodynamical relativistic planar jets. I. Linear evolution and saturation of Kelvin-Helmholtz modes 
    Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Sol, Helene (2004-07-27)
    The effects of relativistic dynamics and thermodynamics in the development of Kelvin-Helmholtz instabilities in planar, relativistic jets along the early phases (namely linear and saturation phases) of evolution has been ...
  • Stability of three-dimensional relativistic jets: implications for jet collimation 
    Perucho, Manuel; Marti, Jose-Maria; Cela, J. M.; Hanasz, Michał; de la Cruz, R.; Rubio, F. (2010-05-24)
    The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale jets are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities. Numerical ...
