“…A study by Heufer et al [8] suggests that reactivity of longer carbon chain alcohol fuels is equivalent to their corresponding alkanes. Compared to low carbon alcohols, n-pentanol has higher energy density, higher boiling point, lesser hygroscopicity and corrosiveness [9]. Gautam et al [6] conducted experimental investigations on combustion characteristics of gasoline and gasoline blended with higher alcohols (n-propanol, n-butanol and n-pentanol).…”

“…In their second study [18], the unstretched flame speed was evaluated using a non-linear expression proposed by Kelly et al [20] for same conditions of temperature and pressure. Nativel et al [9] also used the spherical flame method for mixture temperatures of 353, 433 and 473 K at 1 bar pressure and equivalence ratio range Φ = 0.7 -1.5.…”

Long chain alcohols are potential fuels for engine applications, however, their combustion characteristics need to be adequately investigated compared to short chain alcohols (C 1-C 4), especially at high mixture temperatures, and other conditions relevant to engine temperatures. In the present work, meso-scale diverging channel method has been used to measure the laminar burning velocity of n-pentanol+air mixtures at elevated temperatures due to existence of very limited data at higher mixture temperatures (~ 473 K). The present experiments are carried out at atmospheric pressure with unburnt mixture temperature varying up to 560 K. The dependence of laminar burning velocity on temperature was correlated using the power law: , where α is the temperature exponent. The results show the existence of a minimum value of α for slightly rich mixtures.

Experimental results of laminar burning velocity of n-pentanol+air mixtures at high temperatures were compared with the present model and other kinetic models from the literature. The skeletal model accurately reproduces the measurements at various conditions.

Of several higher alcohols such as pentanol, hexanol, octanol, decanol, dodecanol, phytol, and fusel oil, pentanol isomers have recently received remarkable attention as alternative fuels for diesel engines because they emit less greenhouse gases and harmful pollutants. Because of great potential as a blending component and physicochemical properties of pentanol, binary blends such as diesel/pentanol and biodiesel/pentanol and ternary blends such as diesel/biodiesel/pentanol were mainly studied in the conventional diesel engine. Quaternary blends of diesel, biodiesel, straight vegetable oil, and pentanol were also investigated. Very few information related to the application of pentanol to advanced compression ignition (CI) engine is available in the literature. The diesel/pentanol blends coupled with exhaust gas recirculation (EGR) technology could simultaneously reduce NOx and soot emissions from CI engine. Further, diesel/pentanol blends generally produced higher CO and hydrocarbon (HC) emissions than did diesel fuel. However, CO and HC emissions were significantly reduced by mixing the cetane improver with the blends. Up to 45-50% n-pentanol/diesel blends can be safely used in diesel engines without any engine modification or any additive. However, in terms of kinematic viscosity, lubricity, and oxidation stability of diesel/pentanol blends, the use of pentanol should be limited to concentrations below 10%. Generally, in the studies of biodiesel/pentanol blends in CI engines, the reduction of CO, HC, NOx, and smoke emissions was observed compared to neat biodiesel. For ternary blends, diesel/biodiesel/pentanol blends were mainly investigated by the researchers. The emission characteristics in terms of CO, HC, NOx, and smoke opacity showed the different trends according to the pentanol proportion in the ternary blends, particularly <10% or more than 10%. To increase the biofuels in the CI engine, more studies for the quaternary blends of pentanol are required.

“…Julien et al [15] built a counterflow particulate-fuel burner and used it to measure the burning velocities of aluminum/air mixtures but did not eliminate the flame stretch. In contrast to gaseous or liquid fuels, this revealed that there are challenges in LBV measurements of mixtures in the presence of solid particulates via conventional techniques, such as using counterflow flames [16], spherically expanding flames [17], or flat flames [18]. To determine the burning velocity of particulate fuels, a conical Bunsen flame technique was used by WPI researchers [5,[19][20][21].…”

The effect of NaCl as an extinguishing agent on metal dust fires require further exploration. This paper reports the results of an experimental study on the performance of micron-sized NaCl powders on hybrid aluminum–methane–air flames. NaCl particles with sub-10 μm sizes were newly fabricated via a simple solution/anti-solvent method. The combustion characteristics of aluminum combustion in a methane-air flame were investigated prior to the particle inhibition study to verify the critical aluminum concentration that enables conical aluminum-powder flame formation. To study the inhibition effectiveness, the laminar burning velocity was measured for the established aluminum–methane–air flames with the added NaCl using a modified nozzle burner over a range of dust concentrations. The results were also compared to flames with quartz sand and SiC particles. It is shown that the inhibition performance of NaCl considerably outperformed the sand and SiC particles by more rapidly decreasing the burning velocity. The improved performance can be attributed to contributions from both dilution and thermal effects. In addition, the dynamic behavior of the NaCl particles in the laminar aluminum–methane–air flame was investigated based on experimental observations. The experimental data provided quantified the capabilities of NaCl for metal fire suppression on a fundamental level.
