Abstract:
Investigation of turbulent flows, and, in particular, the flows arising due to Raleigh–Taylor instability, is a fundamental hydrodynamic problem. Due to complexity of direct numerical calculation and scantiness of a parametric approach one has to look for new methods for the description of turbulent flows. A principally new approach to studying of the problem is proposed in this work, i.e. the development of a semi-parametric model by means of a neuronet analysis of the experimental (calculation) data. Below we describe a technique for coding the initial physical fields aimed at the creation of neuronet input vectors, present a stable description of Raleigh–Taylor mixing processes, show a possibility in principle to predict the development of turbulent flows.
