Both the dynamics and observational properties of relativistic jets are determined by their interaction with ambient medium. A crucial role is played contact discontinuity at jet boundary, which in presence collimation may become subject to Rayleigh-Taylor instability (RTI) Richtmyer-Meshkov (RMI). Here, we study evolution these instabilities non-magnetized using special three-dimensional hydro...

We report on recent extensions and improvements to the Legolas code, which is an open-source, finite element-based numerical framework solve linearised (magneto)hydrodynamic equations for a three-dimensional force- thermally balanced state with nontrivial one-dimensional variation. The standard Fourier modes imposed give rise complex, generalised non-Hermitian eigenvalue problem solved quantify...

The linear stability of the dissipative Taylor-Couette flow with an azimuthal magnetic field is considered. Unlike ideal flows, the magnetic field is a fixed function of a radius with two parameters only: a ratio of inner to outer cylinder radii, eta, and a ratio of the magnetic field values on outer and inner cylinders, muB. The magnetic field with 0<muB<1/eta stabilizes the flow and is called...

We have detected unique hydrodynamic topology in thin air film surrounding the central dimple formed during drop impact on an immiscible liquid pool. The pattern resembles spinodal and finger-like structures typically found various condensed matter systems. However, similar entrapped gas films impacts solids or liquids not been reported to date. thickness profile associated dewetting dynamics l...
