Abstract: Three-dimensional (3D) numerical magnetohydrodynamic (MHD) simulation is carried out for the two successive slow CMEs with initial speeds of 240 km/s and 410 km/s, in order to study a scenario of the collision process of these two CMEs. Based on the 3D numerical results, the energies including the kinetic, magnetic, internal and gravitational potential energy are studied in detail. Energy analysis during the propagation and interaction of the two CMEs show that we are able to in principle reproduce the super-elastic collision process for this scenario which supports the conclusions made by C.Shen et al. (2012) (hereinafter referred to as paper 1) for a comprehensive picture of a unique collision between two CMEs for the 2 November 2008 event observed by STEREO Spacecraft in the heliosphere.
