Interaction of Particle-Particle and Particle-Bubble in Water:Molecular Dynamics Simulation

doi:10.16182/j.issn1004731x.joss.201708020

Abstract

Abstract: Graphene and a bulk of gas were used to represent a part of particle and a part of bubble, respectively, and their interactions in liquid water with dissolved gas were simulated. Changes of the structural phase diagram, the gas density, and the potential of mean force were analyzed. The results show that the interactions of particle-particle and particle-bubble are both related to the nanobubble bridges therein. The forming processes of nanobubble bridges were shown in details. The range of nanobubble bridges and the energy change of the system were quantitatively calculated.

Key words: hydrophobic interaction, molecular dynamics, nanobubble bridge, potential of mean force
