Abstract

An interface like structure observed during heat transfer in fluid near the critical point has been analyzed using a molecular dynamics (MD) method for a simple fluid modeled by the Lennard-Jones (12-6) potential. Under the condition that a temperature gradient exists, MD simulations at supercritical pressure reproduced a structure which is similar to the normal liquid - vapor interface observed at subcritical pressure. Some characteristics of the interface like structure, such as density profile, interface thickness, and interfacial tension, are compared with those of a subcritical liquid - vapor interface. The predicted value of the supercritical interfacial tension is compared with the value that was estimated using a theory of hydrodynamic instability due to the interfacial tension.
