Compatibility prediction of the base oil-additives mix in lubricants

Abstract

The project has treated three study cases about some challenges for different lubricant applications including thermal engines and industrial lubricants. The first study case is about the validation of some methods which predict the compatibility of Olefin Copolymers and a Base Oil Called YB4+ using Molecular Dynamic procedure, by a comparison of Solubility Parameters. The Second is about Gyration Radius, a property linked with the Viscosity. Then, at the end, the methodology is applied to real system for industrial applications, e.g. compatibility in terms of solubility parameters and the impact of the concentration of additives using an energetic approach looking for study the impact caused by the concentration of the additive, it was observed that it could be possible to model big real molecules with little ones and then find a optimum lubricant defined by the method.
