Study of Estimation Methods for Hydrogen Content and Heat of Combustion of Aviation Turbine Fuels.

摘要

The value of using the hydrogen content of jet fuel as a measure of the fuel's combustion performance and an evaluation of the use of correlation equations to accurately calculate a fuel's hydrogen content based on other measured fuel properties (aniline point and gravity) have been documented. Subsequently, new correlation equations for calculating the hydrogen content and the heat of combustion of jet fuels have become available. It is the purpose of this report to evaluate these new equations and to determine their suitability for use in jet fuel specifications. A study was performed to determine the suitability of several newly developed equations for calculation of hydrogen content and net heat of combustion of JP-4 and Jet A fuels. Results of the evaluation indicate that two of the five hydrogen content equations and three of the four net heat of combustion equations are unconditionally acceptable for both JP-4 and Jet A fuels.
