Schemes for Interpartical Interaction Forces in Multiphase Shan-Chen Model

A single-component multiphase lattice Boltzmann model which combines effective mass function with special potential in calculating interparticle potential based on Shan-Chen model is proposed.Accuracy of the model is verified by simulating single-component phase change process.Different equations of state are explored in the model.It shows that the model has many advantages: It tallies with the Maxwell construction more precisely;The maximum magnitude of spurious current is smaller and the range of simulation temperature is greater.Laplace tests is carried out and simulated results are in conformity.
