Abstract
Cyclone separators play an important role in industry to separate solid particles from the fluid flow. This paper tries to estimate the internal flow behavior and performance of cyclone separators with various external mist injections by three-phase numerical simulations and find out comparatively the most appropriate mist injected locations for industrial applications. The external mist injection was described by Largrange’s approach, gas phase and particle phase were considered modelled by Euler-Lagrange approach following the previous researches. The internal flow behaviors and performance of cyclone separators have been numerically investigated and compared by using the Reynolds Stress Model(RSM) for modeling turbulent flow. The numerical models utilized in this study have been validated by the experimental work from previous studies. The results show that, the performance of cyclone separators is significantly affected with adjustment of the mist injection location. The inverse weighted sum performance of the best design is 9.273% and 3.369% higher than the worst design and overall averaged performance, respectively.
