Measurements were made for ten compositions over the entire concentration range from 0 to 1 mole fraction of ammonia, namely, 0.0, 0.1905, 0.2683, 0.3002, 0.4990, 0.5030, 0.6704, 0.7832, 0.9178, and 1.0 mole fraction of ammonia. In total, 316 experimental data points were obtained. The expanded uncertainty, with a coverage factor of k = 2, of the thermal conductivity, pressure, temperature, and concentration measurements is estimated to be 3%, 0.05%, 0.02 K, and 0.0014%, respectively. The average absolute deviation (AAD) between the measured and calculated reference values for pure water and ammonia is 1.3% and 1.4%, respectively. Correlation models for the thermal conductivity of liquid ammonia + water mixtures were also developed. | | En ligne : | http://www.sciencedirect.com/science/article/pii/S0140700713000315 |
