“…Figure presents the correlation between FMCR and flame height for BK-5 and Jet A1. The flame height and FMCR relationships of Jet A1 and its counterpart were not linear functions expressed in diffusion flame theory. , The results, however, agreed with the work of Roper et al and our previous study . This phenomenon is attributed to the high amount of aromatic in Jet A1, which leads to high soot concentration, and an increase in the length of the soot oxidation region in the flame, resulting in a massive rise in the visible flame length.…”

“…The bioparaffin prototypes, named Bio-P1 and Bio-JP2, were blended with Jet A1 with proportions up to 5 and 10% volume for making biokerosene that satisfied the ASTM D1655. In addition, soot formations of the bioparaffins, dodecane, and their mixtures with variable levels of propyl-benzene of 10, 20, and 25 vol % were determined and compared to each other, which are also presented in our previous work . Dodecane and propyl-benzene were selected as reference fuels because they are common aviation fuel surrogates for the paraffin and aromatic classes, respectively.…”

Performances, emissions from the gas turbine engine, and soot formations in diffusion flames of kerosene (Jet A1) and its mixture with 5% by volume bioparaffins (known as BK-5) are reported in the present study. A Rover 1S/60 gas turbine engine was used for recording performance parameters and emissions. Soot characteristics were investigated in smoke-free coannular wick-fed diffusion flames. This study is the next step that must be performed in the certification process of a new aviation biofuel before it is tested in the aircraft. The results show that BK-5 produced a similar performance against Jet A1. Throughout the whole power range under investigation, BK-5 emitted 3.4% NOx higher than Jet A1, while Jet A1 released CO and HC at the rates that are, respectively, 1.8 and 4.5% greater than its counterpart. The soot emissions from the BK-5 and Jet A1 were comparable across the measured flame height range. The results encouraged future studies to carry out the modern engine and flight tests. The production process for bioparaffins employed in this work has been demonstrated to be viable and appropriate for tropical developing nations. The current process should also continue to be improved by eliminating high-distillation temperature components in bioparaffins.

“…Hong et al [20] quantified the total soot volume of aviation bio-paraffin blended with 10-25 vol% of propylbenzene to study the soot formation in a co-flow laminar diffusion wick-fed flame using the light extinction method. It was reported that the soot concentration for bioparaffin is only marginally different from those of straight-chain dodecane.…”
