Molecular Dynamics Simulation of Binary liquid mixture Phase Separation and Glass Transition

Abstract

This paper aims to study the phase separation of binary liquid mixture and two-phase glass transition process by using the method of molecular dynamics (MD) simulation. To this end, mainly taking B particle as research object in this paper, the temperature changes after the two-phase separation of binary liquid mixture were observed and compared. Through the study, it’s found that under the external pressure, phase separation phenomenon appeared in the binary liquid mixture, and there existed the differences in the two-phase glass transition temperature after separation. Therefore, the phase separation of binary liquid mixture and glass transition may vary with the temperature, resulting in non-uniform microscopic phenomena.
