ABSTRACT

New experimental data on the thermal conductivity of trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) are reported that allow the development of wide-range correlations. These new experimental data, covering a temperature range of 204 to 453 K at pressures from 0.1 to 67 MPa, are used to develop a correlation for the thermal conductivity. The experimental data reported here have an uncertainty of 1% for liquid and supercritical (density greater than 700 kg*m 3), 1.5% for vapor and supercritical (pressure = 1 MPa and density less than 200 kg*m 3), 3% for supercritical (200 kg*m 3 = density = 700 kg*m 3), and 3% vapor and supercritical (pressure less than1 MPa). On the basis of the uncertainty of and comparisons with the present data, the thermal-conductivity correlation for R1233zd(E) is estimated to have a relative expanded uncertainty ranging at a 95% confidence level from 1% to 4% depending on the temperature and pressure with larger uncertainties in the critical region.
