Abstract
A new interpretation of the known results of simulation of the turbulent regime at the time before the stagnation stage of fusion implosion is stated. For this aim, the universal turbulence energy spectrum obtained by the authors with a scaling law −8/3, which corresponds to the exact solution of one-dimensional Euler equations for the dynamics of a compressible medium, is used. It is stated that the scaling law −8/3 has more relevance in comparison with the Kolmogorov spectrum of −5/3 in the inertial sub-range of scales for the compressible turbulence at this stage of fusion implosion. A possible mechanism for the occurrence of the anisotropic spectrum −8/3 in turbulence associated with hydrodynamic instability of rotation of the medium behind the shock wave front is considered.
