The Applications of Free Volume Models to the Evaluation of Transport Properties of Square Well Fluids
Abstract:
This paper proposes a method of testing the free volume models for fluid transport properties by the MD simulation data for square well fluids. Several commouly used free volume models for viscosity and thermal conductivity are evaluated by the method,and the results show that the model proposed by this author is superior to others. Two important conclusions have been derived: a unified model can be applied to both viscosity and thermal conductivity, and the transport properties of liquld and gas (vapor) phases can be correlated simultaniously by the model with unified parameters. The conclusions approached here are of significance to the systems of practical interests.
