Introducing hydrogen bonding contribution to the Patel-Teja thermal conductivity equation of state for hydrochlorofluorocarbons, hydrofluorocarbons and hydrofluoroolefins

Abstract

The hydrogen bonding contribution has been added to the Patel-Teja thermal conductivity equation of state for the first time to compute the thermal conductivity of the liquid mixtures containing hydrochlorofluorocarbons, hydrofluorocarbons and hydrofluoroolefins. The coefficients of the pure fluids are determined by using 4 strategies. Then an appropriate mixing rule and the cross association terms have been used, and the present model is used for binary and multicomponent mixtures of the liquid phase. The accuracy of this model has been determined through the thermal conductivities of 12 binary liquid mixtures and 1 ternary liquid mixture. Furthermore, the model is used with and without binary interaction parameters to test the predictions of the present thermal conductivity equation of state. The predictions of this model show that the application of hydrogen bonding contribution and the first strategy results in generally low deviations for the liquid mixtures (Overall AAD% is 7.15% and 6.18% without and with binary interaction parameters, respectively).
