Abstract

A statistical analysis of calculations of the Rayleigh-Taylor instability development was performed. The objective of this analysis was to estimate the possibility of predicting integral characteristics of late calculation states (the mixing zone width Δ is considered) by their initial states without numerical simulation. At initial time points, the density distribution fields were described by the parameter set {c i }, after which the function Δ\( (\vec c) \) was approximated by points in the space of the description parameters. The accuracy of prediction of the approximating function was estimated by test samples.
