The effect of viscosity and resistivity on Rayleigh–Taylor instability induced mixing in magnetized high-energy-density plasmas

This work numerically investigates the role of viscosity and resistivity on Rayleigh-Taylor instabilities in magnetized high-energy-density (HED) plasmas for a high Atwood number plasma beta regimes surveying across magnetic Prandtl numbers. The numerical simulations are performed using visco-resistive magnetohydrodynamic (MHD) equations. Results presented here show that inclusion self-consistent system drastically changes growth instability (RTI) as well modifies its internal structure at smaller scales. It is seen has stabilizing effect RTI. Moreover, inhibits development small scale structures also morphology tip RTI spikes. On other hand, reduces field stabilization supporting structures. spikes to be unaffected by presence system.
