Numerical Analysis of the Evolution of Hydrodynamic Instabilities and Vortex Generation Associated With Collisionless Shocks in Laser‐Produced Plasmas
ABSTRACT We numerically studied laboratory experiments that generate turbulence by colliding asymmetric supersonic counterstreaming plasmas driven by laser‐produced plasma. After the interaction of these two flows, the resulting reflection shocks and contact discontinuity exhibit curvatures due to the asymmetry, driving the growth of hydrodynamic instabilities such as Kelvin‐Helmholtz and Richtmyer–Meshkov instabilities. This leads to the development of turbulence in the shocked plasma. We numerically calculate proton radiographs through this plasma, assuming an electric field via quasi‐static force balance in the equation of motion of electrons. Using neural networks, we demonstrate the reconstruction of unknown electric fields in the plasma from the synthetic proton radiography data.
