= Wong–Sandler mixing rule
{wiki=Wong–Sandler_mixing_rule}
The Wong–Sandler mixing rule is a numerical method used in thermodynamics, particularly in the field of fluid mixture modeling. It is often employed in the context of defining the properties of mixtures in systems where different components exhibit non-ideal behavior. This mixing rule is an extension of the traditional mole-fraction averaging, and it helps to improve the prediction of phase equilibria and thermodynamic properties of mixtures, especially in systems with strong interactions between different components.
