Abstract: The initial geometry effect on collective flows, which are inherited from initial projectile structure, is studied in relativistic heavy-ion collisions of $^{12}\mathrm{C}+^{197}\mathrm{Au}$ by using a multiphase transport model (AMPT). Elliptic flow (${v}_{2}$) and triangular flow (${v}_{3}$) which are significantly resulted from the chain and triangle structure of $^{12}\mathrm{C}$ with three-$\ensuremath{\alpha}$ clusters, respectively, in central $^{12}\mathrm{C}+^{197}\mathrm{Au}$ collisions are compared with the flow from the Woods-Saxon distribution of nucleons in $^{12}\mathrm{C}$. ${v}_{3}/{v}_{2}$ is proposed as a probe to distinguish the pattern of $\ensuremath{\alpha}$-clustered $^{12}\mathrm{C}$. This study demonstrates that the initial geometry of the collision zone inherited from nuclear structure can be explored by collective flow at the final stage in heavy-ion collisions.
