Antimisting Kerosene Atomization and Flammability.
Abstract
Experimental results are presented exploring various parameters found to affect the flammability of antimisting kerosene (Jet A + polymer additive). Digital image processing has been integrated into a new technique for measurement of fuel spray characteristics. This technique has been developed to avoid many of the error sources inherent to other spray assessment techniques and has applied to the study of engine fuel nozzle atomization performance with Jet A and antimisting fuel. Aircraft accident fuel spill and ignition dynamics have been modeled in a steady state simulator allowing flammability to be measured as a function of airspeed, fuel flow rate, fuel jet Reynolds number and polymer concentration. The digital imaging technique has been employed to measure spray characteristics in this simulation and these results have been related to flammability test results. Scaling relationships have been investigated through correlation of experimental results with characteristic dimensions spanning more than two orders of magnitude.
