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

This article analyzes the results of a numerical study of the effect of the initial injection mass and the initial temperature of the oxidizer on the tridecane (C13H28) combustion process. During the research work, the KIVA software package was used. Based on the results of the performed numerical simulation, the distribution of the temperature of the fuel droplets and the concentration of CO2 were obtained for various values of the mass of injected liquid fuel in the combustion chamber. After analyzing the results of the study, it turned out that the effective initial mass of fuel injection is 9 mg. Having studied the dependence of the maximum temperature and concentration of carbon dioxide in the combustion chamber, formed as a result of fuel combustion, on the initial temperature of the oxidizer in the combustion chamber, it was concluded that the value of the effective initial temperature of the oxidizer is 900 K.
