Method for prediction of thermophysical, acoustic and structure properties of liquids with the framework of cluster modelGennady Melnikov2, •Vyacheslav Verveyko1, Marina Verveyko1, and Yury Melikhov11Kursk State University, Kursk, Russia — 2South-West University, Kursk, Russia

The proposed by authors distribution function of clusters with respect to number of particles allows to obtain the isothermal equation of state, which provides the method for prediction of thermophysical, acoustic and structure properties of simple liquids without a knowledge of an explicit form for the radial distribution function and adjustable intermolecular interaction potential. As well, structure and relaxation processes could be analyzed too.

The calculations are evaluated for liquefied noble gases and several hydrocarbons. Their comparison with the known experimental data shows a high exactness of the proposed method and its advances for the prediction of the mentioned properties in a wide range of state parameters.
