New Findings from National Institute of Standards & Technology Describe Advances in Chemical and Engineering Data
January 13th, 2012
According to the authors of a study from Boulder, Colorado, "New experimental data on the thermal conductivity of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) are reported that allow the development of wide-range correlations."
"These new experimental data, covering a temperature range of (242 to 344) K for R1234yf and (203 to 344) K for R1234ze(E) at a pressure range of (0.1 to 23) MPa, are used to develop correlations for the thermal conductivity. The experimental data reported here have an uncertainty of less than 1 % for liquid measurements and for gas at pressures above 1 MPa, increasing to 3 % for gas at low pressures...
