Measurements on the thermal conductivity of three fuel blends containing a biodiesel compound methyl laurate + diesel compounds: n-Undecane, n-dodecane, n-tridecane

Abstract

Recently, biodiesel has received tremendous attention from a lot of scientists as a biodegradable, renewable and high-potential fuel which could be used directly or blended with diesel in internal combustion engines. The adequate thermophysics properties of fuel are required to model the process of fuel spray, atomization and combustion accurately. In this work, three fuel blends containing methyl laurate and n-undecane, n-dodecane, n-tridecane were prepared and an important transport property—liquid thermal conductivity of which were measured by the transient hot wire method system. The measurement was conducted at temperature ranging from 292 K to 362 K at atmospheric pressure with the mass fraction of methyl laurate being nearly 0.2000, 0.4000, 0.6000 and 0.8000 (by weight) in the binary mixtures. Furthermore, the relationship between the experimental results and temperature and concentration of methyl laurate were correlated as a function. The uncertainty of the experimental system is less than ±2.0%.
