A model is constructed for the origin of the double-humped structure found inthe di-hahron azimuthal correlation on the away-side in heavy ion collisions.The parameters in the model are determined by fitting $\Delta\phi$ azimuthaldistribution in central Au+Au collisions at RHIC given by STAR collaborationwhen the trigger momentum is in $3-4\rm {GeV/c}$ and the associated particlemomentum is in $1.3-1.8\rm{GeV/c}$. Then we apply our model to the semi-centraland peripheral Au+Au collisions at RHIC and the responding $\triangle \phi$azimuthal distribution are reproduced respectively. Our results show that thetransverse flow effect plays an essential role in the experimentally observeddi-hadron azimuthal distribution structure. The spread of the hard partoncreation point and initial moving direction is also necessary for thedouble-humped structure.
