Abstract: (AIP)
We have performed numerical simulations of weakly and strongly magnetized relativistic jets embedded in a weakly and strongly magnetized stationary or mildly relativistic (0.5c) sheath using the RAISHIN code. In the numerical simulations a jet with Lorentz factor γ = 2.5 is processed to break the initial equilibrium configuration. Results of the numerical simulations are compared to theoretical predictions from a normal mode analysis of the linearized RMHD equations describing a uniform axially magnetized cylindrical relativistic jet embedded in a uniform axially magnetized moving sheath. The prediction of increased stability of a weakly‐magnetized system with mildly relativistic sheath flow to Kelvin‐Helmholtz instabilities and the stabilization of a strongly‐magnetized system with mildly relativistic sheath flow is confirmed by the numerical simulations.- 95.75.Pq
