Abstract
The creation of alternative fuels for the aeronautical sector generates a need to know the safety properties of the same, among them is the flammability limits. The aim of this manuscript is to experimentally determine the flammability limits of Farnesane, Jet Fuel and mixtures of 10% (F10) and 50% (F50) in mass of Farnesane at atmospheric pressure with temperature variation. For this purpose, an experimental bench was built according to ASTM E681, in which the flame propagation is analyzed visually and contains a bottle of 20.716L of borosilicate glass. A total of 161 tests were performed and the flammability limits of the samples were determined at atmospheric pressure and temperature ranging between 140 and 210 ° C, the results are compared with the scientific literature in order to validate the experiments. For the lower flammability limit was an estimated error of 10.4% for Farnesane and 9.6% for Jet Fuel compared to the value found in the safety data sheet at atmospheric pressure and 25 ° C. The tests of the upper flammability limits of Farnesane were limited to a temperature of 190 ° C, as it is found in the auto ignition region. The experimental curve of the upper flammability limit was displaced in relation to the theoretical curve.
