“…This finding is unusual but not unique. Vaughan (1988) reported a similar phenomenon. Vaughan experimentally investigated the effect of the chamber length of a small vaneinduced uniflow cyclone on the particle separation efficiency for aerosol sampling purpose.…”

A novel uniflow cyclone design was evaluated using three prototype cyclones. For the first two, the efficiency and Euler number were determined using airborne solid particles with a number mean diameter of 12.5 m. Then a larger scale prototype based on the optimized geometry was compared with an existing conventional high efficiency cyclone and a vane-induced uniflow cyclone, using mineral oil droplets with a number mean diameter of 8.9 m. Both sets of experiments showed that the newly designed cyclone had a higher efficiency at a higher pressure requirement, in addition to the feature of a small footprint.Un nouveau modèle de cyclone uniflow aétéévaluéà l'aide de trois cyclones prototypes. Pour les deux premiers cyclones, l'efficacité et la perte de charge ontété déterminées avec des particules solides transportées par le gaz de diamètre moyen en nombre de 12,5 micromètres. Puis un prototypeà plus grandeéchelle basé sur la géométrie optimisée aété comparéà un cyclone conventionnel existantà haute efficacité età un cyclone uniflowà ailettes, en utilisant des gouttelettes d'huile minérale d'un diamètre moyen en nombre de 8,9 micromètres. Les deux séries d'expériences montrent que le nouveau modèle de cyclone a une plus grande efficacité ou une demande de pression moins grande, en plus d'être plus compact.

“…In flow pattern visualization experiments performed by Vaughan (1988), it was shown that the general flow pattern in an axial flow cyclone has three concentric vortexes. The flow following the outer vortex spirals down, forms a inner vortex that spirals upward, and then finally spirals downward again at an even smaller vortex size to the V.F.…”

“…Wedding, Welgand, and Carney (1982) proposed a dichotomous sampling head using an axial flow separator design to match the human thoracic penetration curve. Vaughan (1988) developed a simple axial flow cyclone consisting of a helical channel, a cylindrical body, and an aerosol exit tube. Six configurations with three cyclone body lengths and two channel depths were tested under cyclone flow rates ranging from 1.1 to 4.16 lpm.…”

“…It was one of the earliest application of axial-flow cyclone. Vaughan (1988) designed, constructed and tested a simple axialflow cyclone which consists of helical channel, cylindrical body and exit tube. He concluded the axial-flow cyclone had smaller cut off diameter than tangential cyclones of similar device size.…”

Particulate matter (PM) is one of the major indoor air pollutants in the subway-underground stations in Korea. Various kinds of PM removal methods such as a roll-filter, auto-washable air filter, demister, and electrostatic precipitator are applied in the air handling unit (AHU) of subway station. However, those systems are faced with operation and maintenance problems since the filter-regeneration achieved by air or water jet is often malfunctioned due to the high load of particulates. The filter material also needs periodic replacement. In this study, we designed a novel particle removal system with minimized maintenance requirement compared to above mentioned filter systems. The new system named as panel-type cyclone system was suggested and the key part of the system was developed based on the axial-flow cyclone where the air flow pattern lies on the same axis with air stream through passing the AHU. The shape of axial-flow cyclone was optimized to remove 50% of 2.5 μm-sized particulate matters with minimal pressure drop by using the tool of computational fluid dynamics. We believe that the novel axial-flow cyclone system is cost-effective and efficient way of removing particulate matters in the size range of 1-10 μm in the AHU of subway station or buildings.
