N2 - Two different scenarios of spiral vortex breakdown are observed experimentally and further investigated numerically in the swirl flow into a conical diffuser. The primary spiral vortex breakdown is observed near the inlet of the conical diffuser in cases of the cone angle β > 3 ° . The secondary spiral vortex breakdown occurs at the exit of the cone at β ≤ 3 ° . Also, the coexistence of two spiral vortices is observed. For the first time, we have visualized and explained the reasons of these observations.
