In this Letter, the numerical simulation of axisymmetric hydrodynamic relativistic jet propagation was performed by solving the hydrodynamic relativistic Euler equation using the computer code PLUTO [Mignone et al., Astrophys. J. Suppl. Ser. 170, 228 (2007)]. The detailed flow features involved in this relativistic jet propagation has been thoroughly discussed in this present numerical study. The effect of the jet Lorentz factor (Γj) on the shock–turbulence interaction has been studied by analyzing the divergence of the Lamb vector (L=ω×U). The strong coexistence of two layers ·L<0 and ·L>0 enhances the momentum transfer due to energy difference, causing turbulence amplification.
