High compression of matter by hyper-spherical shock waves
Research Areas
  • Physics - Plasma and fluid
A novel compression scheme is proposed, where hollow targets with specifically curved structures are initially filled with uniform matter, being driven by a converging shock wave. Self-similar dynamics is analyzed for the converging and diverging shock waves. Owing to the enhanced geometrical accumulation, the shock-compressed densities and pressures turn out to be substantially higher than ones achieved by spherical shocks, for which two-dimensional hydrodynamic simulations are demonstrated. Detailed linear stability analysis limited to spherical geometry reveals a new dispersion relation with cut-off mode numbers as a function of specific heats ratio ?, over which eigenmode perturbations are smeared out in the converging phase.
