Methyl pentanoate laminar burning characteristics: Experimental and numerical analysis

Abstract

This study investigated the laminar combustion characteristics of methyl pentanoate (MPe) using the constant volume combustion chamber at the initial pressures and temperatures of 1, 2, and 4 bar and 423, 453, and 483 K, respectively over the equivalence ratios ranging from 0.7 to 1.4. The experimental and simulated peak pressures showed a good trend irrespective of the disparities between both results. The experimental laminar burning velocities agreed well with the simulated laminar burning velocities. Also, laminar burning velocities at the initial temperatures and pressures up to 573 K and 8 bar, respectively were estimated using a deduced empirical formula. Last but not least, the main pathways for the decomposition of MPe were MPe → MPe2J → MPeMJ → MPe3J.
