  Supernova remnant (SNR) G309.2-0.6 has a peculiar radio morphology with two
bright ears to the southwest and northeast, although the main shell outside the
ears is roughly circular. Based on an earlier proposal that the supernova
ejecta has a jet component with extra energy, the dynamical evolution of the
remnant is solved using 3D hydrodynamical (HD) simulation to investigate the
formation of the periphery of the remnant. Assuming the ejecta with a kinetic
energy of $10^{51}$\,erg and a mass of $3~\mathrm{M}_{\odot}$ evolved in a
uniform ambient medium for a time of $\sim 4000$\,yr and the jet component has
cylindrical symmetry with a half open angle of $10^\circ$, the result indicates
that the energy contained in the jet is about $10-15\%$ of the kinetic energy
of the entire ejecta to reproduce the detected profile. This study supports
that the remnant originated from a jet-driven core-collapse supernova.
