二乙二醇二甲醚液相导热系数实验研究

THERMAL CONDUCTIVITY OF DIETHYLENE GLYCOL DIMETHYL ETHER IN LIQUID PHASE

本文利用瞬态单热线法对温度区间233～373 K、压力区间0.1～30 MPa的二乙二醇二甲醚(DMDE)的导热系数进行了实验研究,为替代燃料研究提供了基础数据,导热系数测量不确定度为±2%。实验数据拟合成导热系数关于温度和压力的方程,实验数据与拟合方程计算值的最大偏差为-2.56%,平均绝对偏差为0.91%。

In order to provide the urgent thermophysical data for the research of alternative clean fuels,using transient hot-wire method,the thermal conductivity of liquid diethylene glycol dimethyl ether were measured over the temperature range from 233 to 373 K and pressure range from 0.1 to 30 MPa.The uncertainty of the thermal conductivity was estimated as±2%.The experimental results were correlated as a function of temperature and pressure.The maximum and the average absolute deviation of the experimental values...
