Laminar Flame Characteristics of 2,5-Dimethylfuran (DMF) Biofuel: A Comparative Review with Ethanol and Gasoline

Abstract

Since the early years of the 21st century, the whole world has faced two very urgent problems: the depletion of fossil energy sources and climate change due to environmental pollution. Among the solutions sought, 2,5-Dimethylfuran (DMF) emerged as a promising solution. DMF is a 2nd generation biofuel capable of mass production from biomass. There have been many studies confirming that DMF is a potential alternative fuel for traditional fuels (gasoline and diesel) in internal combustion engines, contributing to solving the problem of energy security and environmental pollution. However, in order to apply DMF in practice, more comprehensive studies are needed. Not out of the above trend, this paper analyzes and discusses in detail the characteristics of DMF's combustible laminar flame and its instability under different initial conditions. The evaluation results show that the flame characteristics of DMF are similar to those of gasoline, although the burning rate of DMF is much higher than that of gasoline. This shows that DMF can become a potential alternative fuel in internal combustion engines.

Research on Numerical Simulation of Pcci Engine: A Review

“…The Kolomogrov scale of flame length, flame velocity, and flame time is defined by the formula (4) (Hoang et al, 2022;Chomiak et al, 1996;D'Ambrosio et al, 2015):…”

Nanotechnology-based biodiesel: A comprehensive review on production, and utilization in diesel engine as a substitute of diesel fuel

“…All of these factors contribute to the essential requirement for clean and environmentally friendly fuels aiming to achieve the net-zero goals (Dong and Sharma, 2023;; V. N. Nguyen et al, 2023b;Zeńczak and Gromadzińska, 2020). Indeed, scientists are looking at many types of biofuels such as biodiesel (V. N. Nguyen et al, 2023a;Radhakrishnan Lawrence et al, 2022;, bio-alcohol (such as ethanol, methanol, propanol) (Labeckas et al, 2018;Truong et al, 2021;Veza et al, 2022), furan-based fuels (such as DMF, MF) (Hoang et al, 2022a;Hoang and Pham, 2021;Vuong et al, 2022), ether (including dimethyl ether and ethyl ether) (Changxiong et al, 2023;Doan et al, 2022;Wang and Yao, 2020), bio-oil (fuels originated from thermochemical conversion of biomass, scrap tire, plastic waste, municipal solid waste) (Kumaravel et al, 2016;Yaqoob et al, 2021), hydrogen (Fernández et al, 2020b;Hoang et al, 2023a), biogas (Bora et al, 2022;V. G. Bui et al, 2022;Chellapandi and Saranya, 2023), and syngas (Fiore et al, 2020;Huang et al, 2019) because they are considered as the great potential replacement for traditional fuels due to the current fuel scarcity.…”
