| Summary: | This paper presents the work conducted as part of
an effort in developing a multidisciplinary assessment framework
for trade off study between technical, economic and
environmental aspects of alternative jet fuels application
specifically in commercial aircraft. At present, empirical
prediction method has been explored so as to be the basis in
predicting the amount of emissions that have a huge influence
towards the environment. An emission prediction model based on
Boeing Fuel Flow Method 2 (BFFMZ) has been adopted and its
accuracy and applicability has been tested on a specified engine
model. The model was then used to evaluate and to compare the
amount of emission emitted due to the combustion of alternative
fuels, namely Camelina- and Jatropha- synthetic paraffinic
kerosene (SPK) with the conventional jet fuel, Jet A. With
emphasis on emissions of nitrogen oxides (NOx) and carbon
monoxide (CO) at take-off and cruise conditions, the results
indicate that the alternative fuels manaeed to - reduce NOx
emissions up to 3 percent but at an expense of increasing amounts
of CO. The effccts of alternative fuels usac-e com~aredto Jet A towards the amount of emissions as well as engine performance
are also discussed in the paper. Overall, the model has proven
acceptable to be incorporated within an assessment framework
for a thorough evaluation of aviation alternative jet fuel to reduce
dependency on the conventional fossil fuel |
