Abstract

The breakdown of tip leakage vortex was examined on a low-speed axial compressor rotor with moderate blade loading. Effects of the breakdown on the rotor aerodynamics were elucidated by Navier-Stokes flow simulations and visualization techniques. The leakage vortex breakdown were observed inside the rotor at a lower flow rate than the peak pressure rise operating condition. The breakdown was characterized by the existence of the stagnation point followed by a bubble-like recirculating region. The onset of breakdown resulted to large expansion of the vortex and disappearance of the streamwise vorticity concentrated in the vortex.
