Surface Tension in Alkali Halide Mixtures.

Surface Tension Prediction of Hydrocarbon Mixtures Using Artificial Neural Network

In this study, artificial neural network was used to predict the surface tension of 20 hydrocarbon mixtures. Experimental data was divided into two parts (70% for training and 30% for testing). Optimal configuration of the network was obtained with minimization of prediction error on testing data. The accuracy of our proposed model was compared with four well-known empirical equations. The arti...

Surface Tension Prediction for Liquid Mixtures

Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...

The Repulsive Potentials in Alkali Halide Molecules

On the basis of literature values of various spectroscopic quantities, the "experimental" five derivatives (1st to 5th) of the repulsive functions at the equilibrium distance were evaluated for the 20 alkali halide molecules, retaining the truncated Rittner model for the attractive forces. A self-consistency test showed that the used experimental values are reliable. Different analytical forms ...
