Hybrid fluid–particle modeling of shock-driven hydrodynamic instabilities in a plasma
Fig. 1. Energy transfer between fluid electrons and particle ions of mass
Fig. 2. Energy transfer between fluid electrons and two species of ions (C:H = 1:1) at density
Fig. 3. Initial conditions for simulations of a piston-driven planar shock propagation through the perturbed interface separating two fluids of different densities.
Fig. 4. Snapshots of the distribution of the logarithm of mass density (in units of g/cm3) at times 2.02 ps (a), 4.04 ps (b), 6.07 ps (c), and 8.09 ps (d), showing the evolution of a single-mode hydrogen/carbon interface. IS denotes the incident shock, RS the reflected shock, TS the transmitted shock, and CRS the convergent reflected shock. As the incident shock wave passes through the plasma interface, it generates a slower second shock in the heavy plasma and a reflected shock running backward into the light plasma. The black contour near the interface encloses the region within which the fractions of both ion populations exceed 10%. This is the so-called ion mixing region.

Fig. 6. (a) Initial conditions for simulation of ion kinetic effects on growth of Rayleigh–Taylor instability. (b)–(d) Snapshots of the distribution of the logarithm of mass density (in units of g/cm3) at times 50 ps, 100 ps, and 150 ps, respectively, showing the evolution of a single-mode heavy/light plasma interface. The black contour near the interface encloses the region within which the fractions of both ion populations exceed 10% (the ion mixing region).
