Development of semi-parametric models of Raleigh-Taylor instability by means of neuronet processing of the results of numerical experiment. (Russian. English summary) Zbl 1131.76329
In recent times theoretical investigations of the turbulent flows are realizing in two directions: the direct numerical modeling on the base of the hydro-dynamic equations and the parametric model construction based on a statistical averaging of initial equations and on an application of semi-parametric relations closing the system. Here the fundamental hydrodynamic problem – the investigation of turbulent flows arising due to Raleigh-Taylor instability – is considered by use a variant of the second ’parametric’ approach. More exactly, the principally new approach for construction of a semi-parametric model by means of a neuronet analysis of the experimental (numerical) data is proposed. A principle possibility to predict a development of the turbulent flows is demonstrated.
