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

Study of the practice of using solid rocket fuels and explosives has determined the existence of an increase in the combustion rate due to turbulence. However, this rule is violated in the case of small-scale turbulence produced by the gasification zone of solid fuel. The incoming heat from the gas phase is partially consumed to maintain the chemical reaction of gasification and partially returns to the gas phase. If the return energy of turbulent motion is high, then the combustion rate decreases.
