The Effect of Vertex Finder and Dust Outlet on Collection Performance in Square Cyclones Separators with Downward Gas Exit

In this study, computational fluid dynamic method is used to predict and evaluate the flow field and collection performance inside square cyclone separators. Two cyclones with different dust outlet were studied using the Reynolds stress model (RSM). The cyclone flow field pattern has been simulated and analyzed with the aid of static pressure, and velocity components. In addition the cyclone collection efficiency based on one-way discrete phase modeling has been investigated. The obtained results demonstrate that collection performance of the square cyclone separator with vertical dust-outlet is very well. The simulation results agree well with the published experimental results.
