Sentence examples for binary interaction coefficients are from inspiring English sources
Critical properties, acentric factors and the binary interaction coefficients are required for the flash calculations.
To achieve more accurate results, binary interaction coefficients are adjusted as a linear function of temperature.
The clustering technique is performed in a way that the components with similar properties (also with close binary interaction coefficients) are grouped together.
Oil composition and properties of each component are shown in Table 2, and the binary interaction coefficients are shown in Table 3.
The basic idea of the delumping calculation is to separate the PR EOS inputs ((a_{i}, b_{i})) for each lumped component from delumping coefficients in the fugacity coefficient formulations, where the binary interaction coefficients are zero.
According to the results, if the selection of components in each pseudo-component is properly chosen and their critical properties, acentric factors and binary interaction coefficients are correctly calculated, the phase equilibrium results will be in good agreement comparing ThPCA and compositional approaches.
The number of independent variables for phase equilibrium calculations does not depend on the number of components in the mixture and non-zero binary interaction coefficients (BICs) are taken into account by our approach.
All data for each pair of components could be correlated using a single binary interaction coefficient, which was found to be independent of temperature and composition.
l pi denotes a special binary interaction coefficient which was proposed to be a linear function of temperature: l_{pi} = l_{pi}^{0} - l_{pi}^{1} (T - T_{0} ) (18 where (l_{pi}^{0}) and (l_{pi}^{1}) are positive adjustable constants reported in the literature (Karamoddin and Varaminian 2013b) for components of interest in this study.
24 and 25 as given below: a = mathop sum limits_{i = 1}^{n} mathop sum limits_{j = 1}^{n} w_{i} w_{j} left( {a_{i} a_{j} } right)^{0.5} left( {1 - k_{ij} } right) (24) b = mathop sum limits_{i = 1}^{n} w_{i} b_{i} (25 where k ij in Eq. 24 is called binary interaction coefficient and is known as an interaction parameter between non-similar molecules.
If there are no non-zero binary interaction coefficients in the lumped fluid description, the delumping array elements from the third element until the end are the same.
