Investigating the laminar burning velocity of 2-methylfuran

Abstract

The laminar burning velocity of 2-methylfuran was investigated using the constant volume method (CVM) at high initial pressure and temperature conditions. The so-called, linear x(p) approximation and a non-linear analytical x(p) relation were used to study the laminar burning velocities of 2-methylfuran fuel. The CVM results were compared to the constant pressure method (CPM) data and numerical results. The CVM and CPM results showed a consistent trend. A percentage deviation of between −8.9% and 8.2% as well as −6% and 8% were observed at initial pressures of 1 and 2 bar when the CVM results were compared to the CPM data while the difference was between −12% and 6% at 4 bar. The numerical results predicted higher laminar burning velocities at all initial conditions when compared to the CVM results. Laminar burning velocity correlations have been obtained from the combined experimental data as a function of the various unburned mixture pressures and temperatures at equivalence ratios of 0.7–1.4. Laminar burning velocities at high unburned mixture temperature and pressure measurement up to 421 K and 8 bar can be obtained from the few experimental data using the correlation in this study.
