摘要

采用流动型量热法实验系统测量了肉豆蔻酸甲酯的比定压热容，温度测量范围为323.20~393.26 K，压力测量范围为0.11~25.12 MPa。实验系统的温度和压力扩展不确定度分别为0.02 K和5 kPa，比定压热容的相对扩展不确定度为1.45%。基于实验数据，建立了一个可用于高压肉豆蔻酸甲酯比定压热容的计算关联式，其计算值与实验值的相对偏差绝对平均值为0.13%，最大偏差为0.38%。

Abstract

The biodiesel

comprised of fatty acid methyl ester and ethyl ester

is considered as an environment-friendly and promising alternative of fuel. The thermophysical properties of biodiesels as well as their components are essential information for the better knowledge of their industrial applications. For instance

in the spray and combustion processes of engine

isobaric specific heat capacity (

) of fuel has a significant influence on its heat-transfer characteristic. In this work

the

of methyl myristate are investigated using a flow calorimeter at the temperature range of 323.20—393.26 K and pressures up to 25.12 MPa. The expanded uncertainties of temperature and pressure are decided to be 0.02 K and 5 kPa respectively

while the relative expanded uncertainty of

is 1.45%. Then based on the experimental data

a correlation is proposed for calculating the

of methyl myristate

and a satisfactory agreement between calculated results and experimental values can be observed

with the average absolute relative deviation and maximum deviation of 0.13% and 0.38% respectively.
