| 概要 | Experimental study was carried out on the vortex breakdown phenomenon in an open cylindrical container with arotating bottom endwall. Vortex breakdown is seen in a certain parameter range of the container aspect ratio H/Rand the rotating Reynolds number Re. The working fluid used wasa water-glycerinmixture. The meridional plane of the cylinder was illuminated by fluorescein sodium,which wasmixed with the working fluid. A velocity map in the meridional plane was definedusing a particle image velocimetry (PIV). Various types of vortexbreakdownwereobserved. Comparison with previous experimental and numerical studies is discussed in detail about the position of stagnation points, bubble size,and differences between present and previous results. |
