摘要

改进了实验室原有的pvT实验台，测量了HFC-227ea气相pvT性质。膨胀法和等容法相结合，仅需一次充注，沿10条定容线测量了共80组实验数据。实验数据的温度范围为310-410K，压力最大到3．2MPa。首先对超临界410K等温线的数据进行了膨胀法分析，建立了压力和密度关系。以此为基础，获得了各条定容线的密度。建立了HFC-227ea的气相状态方程，与已发表的HFC-227ea的pvT数据进行了比较，实验数据的最大压力偏差小于0．07％，与其他人实验数据也符合良好。状态方程还能精确计算气相声速，与实验数据的最大偏差小于0．05％，说明数据和状态方程都是准确可靠的。

Abstract

The Burnett pvT measurement system was improved. Eighty pressure-volume-temperature data points for HFC-227ea in the gaseous phase were measured using Burnett-isochoric methods. HFC-227ea sample was filled in the apparatus only once. The experimental data were collected along 10 isochores for temperatures from 310-410 K and pressures up to 3.2 MPa. The density of each isochore was based on the pressure-density relationship at 410 K

which was obtained from the Burnett analysis. A three-term truncated virial equation of state (EOS) was developed for gaseous pvT property of HFC-227ea. The pvT data and acoustic data calculated with the present viral EOS agree well with the experimental data

respectively.
