... point was observed. At this operating condition, large, unsteady pressure fluctuation at the blade tip was confirmed, and the occurrence of tip leakage vortex breakdown that was clarified by unsteady multipoint pressure measurement and detailed unsteady numerical simulations. Due to the blockage effect...

... breakdown was thus suppressed, thereby forming a self-sustaining unsteadiness. The TLV breakdown was the decisive factor leading to the flow unsteadiness. transonic compressor rotor tip leakage vortex vortex breakdown unsteadiness Proceedings of ASME Turbo Expo 2022 Turbomachinery Technical...

...Abstract Abstract For achieving better fuel-air mixing within a short distance or for improved atomization of liquid fuels counter rotating swirler designs are preferred in gas turbine engine combustors. In this study, vortex breakdown phenomenon is investigated in co and counter rotating...

... for the first time detailed flow visualization photographs of the interaction of the vane passage vortex with the rotor. The appearance vortex breakdown could be identified before and within the rotating passage of the turbine. The measurements were taken in a vertical water channel. Water is used instead...
