Fundamental Study for Shape Ootimizatioii of Cyclone Separator

The purpose o f this study is to predict the effect o f cyclone shape on pressure loss and its efficiency. Generally, the increase o f inlet velocity o f gas improves the separation efficiency, while it results in increasing in the pressure losses. The standard turbulence model with isotropic assumption cannot predict the flow characteristics with Rankine vortex but the R S M (Reynolds stress model) can estimate them properly. Because o f difficulty o f the adoption o f turbulence model, the validation o f C FD model is carried out by comparing with experimental results. It is known that the influence o f the contract cone at a dust corrector is significant on pressure loss and separation efficiency. This study focuses on flow characteristics according to shapes o f the cone, which is made up by angle o f cone. As the results o f computation, the increase o f cone angle increases the separation efficiency and decreases the pressure loss.
