Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The problems and prospects of statistical modeling of energy containing structure of developed turbulent flows are shown.It is shown that the method of RANS can not provide high quality of such models due to unconditional averaging of Navier-Stokes equations.Also, it is shown that high quality of mathematical models can be achieved using the method of autonomous statistical modeling of turbulence ASMTurb, distinctive feature of which is conditional averaging of Navier-Stokes equations over a turbulent and non-turbulent fluid of a turbulent flow.
