Measurement and prediction of speed of sound in ethyl decanoate
摘要
Abstract
Ethyl decanoate, as a member of fatty acid ethyl esters (FAEEs), is one of the main component of biodiesels. In order to obtain the thermophysical properties for the components of the biodiesels, this paper measured the the speed of sound in ethyl decanoate in the temperature range from 298.15 K to 508.15 K along four isobaric lines at p = (0.1, 2, 4 and 6) MPa by the Brillouin light scattering (BLS) method. The correlation for the speed of sound as a function of temperature and pressure is presented based on the experimental data, which provides convenience for engineering applications. The absolute average of relative deviation between the experimental data and the calculated results is 0.28% in the experimental p-T region. Besides, the experimental data of the speed of sound at atmosphere pressure were also used to assess the predictive ability of Wada’s model and the result shows that Wada’s model can be used to predict the speed of sound at atmosphere pressure for ethyl decanoate within a certain temperature range.关键词
