Abstract
The inertial confinement fusion has not been achieved yet. The reasons for this phenomenon are not fully understood. In our opinion, the main factor influencing the decrease in the yield is the evolution of hydrodynamic instabilities due to geometric inhomogeneities (surface roughness, the presence of asymmetric elements etc.). The perturbed density field can result from these inhomogeneities. The results of a theoretical study of the influence of density perturbations on the stability of the boundary under accelerated motion are presented in this paper. The performed numerical simulations are compared with theoretical results.
