“…Li The present work has two key objectives: i) Addressing the scarcity of laminar burning velocity data for n-pentanol+air mixtures at high temperatures by providing new experimental measurements up to a mixture temperature of 560 K using meso-scale diverging channel technique. This method has been used previously for high temperature burning velocity measurements of various gaseous and liquid fuels [27][28][29][30][31][32][33]. ii) Develop a skeletal model for n-pentanol from Sarathy et al [21] high temperature alcohol model and compare its performance with existing models and current experimental data high mixture tempratures.…”

“…3) are formed for certain conditions and these planar flames are used for extraction of laminar burning velocity. The measurements carry an uncertainty of ± 5% and a detailed discussion on same is reported earlier[27,31,34].The laminar burning velocity is calculated using mass conservation principle at the mixture inlet and flame stabilization point ( ).Where, T inlet is the temperature of incoming mixture, A inlet -channel inlet area and T fmixture temperature at flame stabilization location A f -being the flame area.…”

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.

“…8 resume the variation of the preheating temperature on the laminar flame velocity of such surrogate fuel. As predicted, with increase of unburned reactant temperature, the laminar flame speed of surrogate increases because of the increased chemical rates and thermal and mass diffusivities [44,45]. Finally, in order to elucidate the effects of pressure variation on laminar flame speed, measurements were performed for various pressures ranging between P = 0.1-0.8 MPa.…”

“…ignition delay times). Very recently, Katoch et al [101] reported LBV measurements for methanol-air mixtures at temperatures up to 650 K. They point out that older LBV correlations use either a constant temperature exponent α, or one which linearly decreases with equivalence ratio φ, and that the measurements of Sileghem et al [97] were the first time that a parabolic dependence of α on φ was reported. Using a new method involving the stabilization of a near to planar flame in a heated quartz diverging channel, Katoch et al confirmed this parabolic dependence.…”

Transportation of people and goods largely relies on the use of fossil hydrocarbons, contributing to global warming and problems with local air quality. There are a number of alternatives to fossil fuels that can avoid a net carbon emission and can also decrease pollutant emissions. However, many have significant difficulty in competing with fossil fuels due to either limited availability, limited energy density, high cost, or a combination of these. Methanol (CH 3 OH) is one of these alternatives, which was demonstrated in large fleet trials during the 1980s and 1990s, and is currently again being introduced in various places and applications. It can be produced from fossil fuels, but also from biomass and from renewable energy sources in carbon capture and utilization schemes. It can be used in pure form or as a blend component, in internal combustion engines (ICEs) or in direct methanol fuel cells (DMFCs). These features added to the fact it is a liquid fuel, making it an efficient way of storing and distributing energy, make it stand out as one of the most attractive scalable alternatives. This review focuses on the use of methanol as a pure fuel or blend component for ICEs. First, we introduce methanol historically, briefly introduce the various methods for its production, and summarize health and safety of using methanol as a fuel. Then, we focus on its use as a fuel for ICEs. The current data on the physical and chemical properties relevant for ICEs are reviewed, highlighting the differences with fuels such as ethanol and gasoline. These are then related to the research reported on the behaviour of methanol and methanol blends in spark ignition and compression ignition engines. Many of the properties of methanol that are significantly different from those of for example gasoline (such as its high heat of vaporization) lead to advantages as well as challenges. Both are extensively discussed. Methanol's performance, in terms of power output, peak and part load efficiency, and emissions formation is summarized, for so-called flex-fuel engines
