Description
This research concerns climate change mitigation technologies through the investigations of sustainable alternative fuels. The test fuels are analyzed in order to observe the correlation of ignition delay (ID), combustion delay (CD), the negative temperature coefficient region (NTC), and the low temperature heat release region (LTHR), in a constant volume combustion chamber (CVCC) in relation to blended amounts of iso-paraffinic kerosene (IPK) by mass with Jet-A and their derived cetane numbers (DCN). All testing utilizes the ASTM standard D7668-14.a in a PAC CID 510 CVCC. The DCN is calculated using the ID and CD measured over 15 combustion events. The fuel blends investigated were 75%Jet-A blended with 25%IPK, 50%Jet-A50%IPK, and 25%Jet-A75%IPK. The ID of neat Jet-A and IPK are 3.26ms and 5.31ms, respectively, and the CD of the fuels are 5.00ms and 17.17 ms, respectively. The ID between the 75%Jet-A25%IPK, 50%Jet-A50%IPK, 25%Jet-A75% IPK, blends are 3.5ms, 3.8ms, and 4.2ms, respectively. The CD between the 75%Jet-A25%IPK, 50%Jet-A50%IPK, 25%Jet-A75% IPK, blends are 5.8ms, 7.0ms, and 9.4ms, respectively. The DCNs of the following blends were 43.1, 38.7, and 33.5, respectively. The % difference of each of the fuel blends DCN compared to neat Jet-A is: 10.7%, for 75%Jet-A25%IPK, 21.5% for 50%Jet-A50%IPK, and 35.6% for 25%Jet-A75%IPK. Blends with larger amounts by mass of IPK resulted in extended ignition and combustion delays. It is concluded in the apparent heat release rate (AHRR) of each of these fuel blends, that the blends that have larger amounts of IPK blended within them have extended NTC regions, LTHR regions, and decreased ringing intensity during combustion.
