“…For example, the pressure rising rate and the heat release rate of internal combustion engines depend on the mass consumption rate of fuel. However, the mass consumption rate is completely limited by the droplet vaporization rate and the droplet burning rate. − Therefore, the behavior of individual droplets is essential for understanding spray processes. It is necessary to investigate the combustion behavior of an individual droplet before fully characterizing spray combustion.…”

A detailed experimental investigation on the effect of thermal properties on single droplet combustion characteristics has been performed at room temperature and atmospheric pressure under normal gravity with four n-alkanes (n-octane, n-dodecane, n-tetradecane, and n-hexadecane). The evolution of suspended droplet diameter and the global flame over time were obtained using microscopic and direct photography simultaneously. The results show that the n-alkane droplets used in this study exhibited similar D 2-law curve characteristics and the droplet shape of single component is quasi-spherical throughout the whole combustion duration. The n-alkanes with lower boiling point and high volatility present a higher burning rate and shorter combustion duration, and there is no expansion process during the evaporation period. Strong microexplosion and fluctuation on droplet diameter were observed when the thermal properties of the multicomponent are sufficiently different. The reason is that the bubbles nucleate, grow, and rupture continuously by heating the components of lower boiling point and high volatility in multicomponent droplets. The thermal properties and mixing ratio of the components in the multicomponent droplet and the formation position of the bubbles have an important influence on the microexplosive combustion and its intensity. Besides, there is an inverse power relationship between the burning rate constant of n-alkane droplets and initial droplet diameter (D 0 > 1 mm).

“…Some works have been conducted to research droplet combustion of pure n-butanol [28,29], pure biodiesel [30,31] and diesel-biodiesel-alcohol (methanol, ethanol and propanol) blends [22,32,33]. However, only few works were reported on droplet combustion of n-butanol-biodiesel blends.…”

This work was aimed to study droplet combustion which was a foundation of spray combustion. Combustion characteristics of BUT00 (pure biodiesel) and BUT50 (50% n-butanol and 50% biodiesel by mass) were investigated using droplet suspension technology under 1 bar and 900 K. One flame is observed for BUT00 while two flames are observed for BUT50. The flame of BUT00 underwent successively faint luminosity, bright luminosity, soot aggregate and soot spread. The first flame of BUT50 was faint and the second one was similar to that of BUT00 because they were caused by n-butanol and biodiesel combustion respectively. Before the auto-ignition of BUT00, (D/D0) 2 was approximately unchanged at 1.0 and similarity degree (SD) was higher than 97%. Temperature growth rate (TGR) decreased first quickly and then slowly. After the auto-ignition of BUT00, (D/D0) 2 sharply decreased and SD was in the range of 90-97%. The flame heating led to the increase of TGR. For BUT50, obvious fluctuations were found in (D/D0) 2 , SD and TGD. The SD of BUT50 was generally lower than 97%. The (D/D0) 2 of BUT50 included transient heating, fluctuation evaporation and equilibrium evaporation phases. Some characteristic parameters were deterministic although (D/D0) 2 in fluctuation evaporation phase was a non-deterministic process.
