An Experimental Study on Swirling flow in a Cylindrical Annuli
- 발행 : 2002.11.01
초록
An experimental investigation was performed to study the characteristics of turbulent swirling flow in an axisymmetric annuli. The swirl angle measurements were performed by flow visualization technique using smoke and dye liquid. Using the Particle Image Velocimetry method, this study found the time-mean velocity distribution and turbulent intensity with swirl for Re = 20,000, 30,000, 50,000, and 70,000 along longitudinal sections and the results appear to be physically reasonable.
