AERODYNAMIC PERFORMANCE OF REVERSED FLOW VORTEX CHAMBERS.

Pagination or Media Count:
This work presents recent experimental results obtained with unconventional vortex tubes. Experiments were conducted in both the compressible, supersonic and incompressible flow regimes. By proper injection of the fluid a reversed secondary flow pattern is obtained which enhances particle or gas separation processes. The aerodynamic performance of these new vortex or swirl chambers is compared with the data of other investigators employing conventional vortex chambers. A detailed account of the experimental procedures, both successful and unsuccessful, is also included. Secondary flows in both conventional and in the aforementioned swirl chambers are discussed in some detail. Consideration is also given to the factors limiting the maximum rotational velocities obtainable in vortex tubes.
