Figure 4. The collision of two KDCSs. In top panel: the collision between two type-I KDCSs. The parameters are φ1 = 0.93π, φ2 = 0.5φ1. In bottom panel: the collision between type-II and type-III KDCSs. The parameters are φ1 = 0.1π, φ2 = 0.9π. It is seen that the whole collision is elastic, but striking particle transition emerges among the three components during the collision process. The density evolutions are correspond to the component q1, component q2 and component q3 from the top to bottom. The other other parameters are v1 = 0, v2 = −0.1, d1,1 = d1,2 = 5, d2,1 = d2,2 = 0, d3,1 = d3,2 = 15.
