On the design of miniature cyclones for the collection of bioaerosols

Hydrodynamic Simulation of Cyclone Separators

“…The RNG k-ε model showed significant improvement, while the RSM exhibited the best behavior. Pant et al (2002) and Sommerfeld and Ho (2003) have also reported similar observations. Gimbun et al (2005) studied the effect of temperature and inlet velocity on the cyclone pressure drop.…”

Numerical study of the separation efficiency and heat exchange performance in a complex gas–solid separator

“…At this aim, a lot of studies available in literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], developed by many authors, have been widely studied, both numerically and experimentally, with the main goal of increasing the separation efficiency. Multiple studies [1][2][3][4][5][6][7][8] demonstrated the decisive influence of both operating parameters and design on the separation efficiency and pressure drop.…”

“…The CFD-3D analysis is an efficient and economical approach of understanding the fluid dynamics process in complex plants, providing a precious way to evaluate how it is affected by changes of operating conditions and geometric shapes. At this aim, the CFD approach has been used by many authors [1,[8][9][10][11][12][13][14][15]; the papers deal with issues relative to the flow of gas-solid suspensions predicting solid separation efficiency, at different operating conditions, in good agreement with the experimental evidences. Furthermore, in [13][14][15] the authors proved as the Reynolds Stress Model is the suitable turbulent model for cyclone with strong swirling flow.…”

“…At present, in literature, it is proved that the most utilized turbulence modelling is the RSM turbulence model [1,3,[8][9][10][11][12][13][14]. In addition, all these papers simulate isothermal plants while, the present work has to take into account the thermal exchange in its various forms (convection and radiation).…”

Simulation and experimental validation studies on a new type umbrella plate scrubber

“…In order to knowledge their intrinsic pressure drop and flow characteristics, new methods are needed to study the scrubbers' performance. Over the recent years, as computing costs have decreased, computational fluid dynamics (CFD) has led to shift of scientific study and engineering design through experiments to numerical simulation [2,3]. In the environmental engineering, CFD was applied to evaluate the indoor air quality and to simulate the pollution dispersion, and the diffusion of automobile exhaust into canyons or tunnels [4][5][6].…”
