Numerical investigation of interactions between two particles with different sizes

The interactions between two circular particles sedimenting in a two-dimensional infinite channel is numerically investigated by using the lattice Boltzmann equation with a multiple-relaxationtime collision model.The main emphasis in this work is to investigate the effect of the longitudinal dist...The interactions between two circular particles sedimenting in a two-dimensional infinite channel is numerically investigated by using the lattice Boltzmann equation with a multiple-relaxationtime collision model.The main emphasis in this work is to investigate the effect of the longitudinal dist...The International Union of Theoretical and Applied Mechanics(IUTAM)、The Chinese Society of Theoretical and Applied Mechanics(CST
