Abstract
ABSTRACT The aim of the study, which is a blend of triple biofuel CSP and the blended fuel preparation with jet-A for B5 (5% CSP-95% Jet-A), B10 (10% CSP-90% Jet-A), B20 (20% CSP-80% Jet-A), B40 (40% CSP-60% Jet-A), and B80 (80% CSP-20% Jet-A) on GasTurb Details-6. GasTurb-14 software used to perform simulations at different engine speeds. Within the calculations made, the thrust, thrust-specific fuel consumption (TSFC), emission (CO2, CO, NOx) and thermal efficiency values of the fuel blends used in the JetCat-P160 engine were predicted and compared with pure Jet-A fuel. As a result of the simulations, it has been seen that the CSP and Jet-A blends reduce the thrust value to around of 130 N for B20, B40, and B80 fuels with the addition of more than 10% CSP to the blend. TSFC values increase as the biofuel ratio increases and reaches approximately 2 times when the B80 and Jet-A are compared especially at low engine speeds. In addition, the prepared biofuels have a positive effect on reducing the harmful emission of CO value due to the content of O2. At 39 krpm engine speed, the CO value was 0.19% for Jet-A and 0.07% for B80 fuel and as the engine speed increases, it becomes 0.12% for Jet-A and 0.04% for B80 fuel for the maximum speed of 123 krpm. However, biofuels cause reduced combustion efficiency and delayed combustion and so accelerate the formation of NOx especially above 78 krpm engine speed.
