“…Compared with small methyl esters, investigations on FAMEs with longer carbon chains are very limited. Several studies have been conducted on methyl pentanoate, , methyl caproate, − methyl heptanoate, and methyl decanoate . In particular, methyl decanoate with 10 carbon atoms in its alkyl carbon chain is generally deemed as a suitable biodiesel surrogate due to its close physical and chemical properties to biodiesel, such as the density, flash point, and cetane number. , Abboud et al measured the YSI values of methyl butanoate, methyl octanoate, and methyl decanoate to investigate the effects of chain length on sooting tendency of esters.…”

Biodiesel is one of the most promising low-carbon fuels and has been applied in internal combustion engines. In recent years, there have been emerging interests in the application of biodiesel in gas turbines, accompanied by the growing need for carbon reduction in the gas turbine industry. This mini review focuses on the fundamental combustion research of biodiesel and its model compounds, as well as its current application in gas turbines, mainly in the last 15 years. As for fundamental combustion research, selected advances in combustion chemistry and swirl combustion are reviewed. Diversity in molecular structures of biodiesel and its model compounds includes a vast amount of research on fuel molecular structure effects on combustion characteristics, including the effects of the functional group, chain length, and isomeric structure. Swirling flame studies of biodiesel are also reviewed, which focus on the flame shape, flame stability, atomization performance, and pollutant emissions. Combustion performances of biodiesel in aircraft and land-based gas turbine are also highlighted. Furthermore, some prospects of future research of biodiesel combustion with the purpose of gas turbine application are provided.

“…Varieties of RCMs have been reported in the literature used for the investigation of single [30] and two-stage ignition delay of fuels [31,32] and validation of kinetic models at low to intermediate temperature regime [32][33][34][35]. These can be categorised into four main forms; first, the free piston RCMs [36,37] which uses compressed gas to drive a piston inside the cylinder.…”

This work presents a pneumatically operated piston released rapid compression machine (PRRCM) designed at the University of Sheffield that introduces a new set of pneumatic systems to lock/release the piston from its initial position. It is pneumatically operated to compress gas mixture to an adiabatically thermodynamic state and stopped hydraulically. The range of compression ratios of the facility is between 4.4 and 20. The end of compressed gas temperature, T c and pressure, P c obtained within the facility is approximately 1000 K and 22 bar respectively. The performance of the Sheffield piston released rapid compression machine (SHEF-PRRCM) facility has been characterised to ensure a high level of fidelity of experimental data over a range of test conditions. The performance test was conducted for a nonreactive test using nitrogen and argon, the result demonstrated a repeatable pressure trace. Repeatability test for the reactive mixtures was also demonstrated. Further study on ignition characteristics of aviation fuel (Jet A-1) and Banner NP1014 known as Bannersol in SHEF-PRRCM was conducted over T c of 723 K ⩽ T c ⩽ 884 K, P c = 6 and 10 bar at ϕ = 0.75 and 1.0. The influence of pressure, temperature and equivalence ratio was seen on the oxidation of Jet A-1 and Bannersol. The results showed that Bannersol displayed a negative temperature coefficient behaviour and has higher reactivity than Jet A-1. Besides, a comparative analysis of the current facility with other facilities in literature was carried out, the result showed a fair deviation of the current data from literature and these could be attributed to the inherent non-ideality of heat transfer effects in different rapid compression machine and fairly slight differences in the condition tested. This work has demonstrated the competence of the current facility to carry out further studies on combustion and validation of the chemical kinetics of hydrocarbon fuels.
